National Instruments adds Six New I/O Modules for CompactRIO and CompactDAQ Platforms

National Instruments today announced six new C Series modules designed for NI CompactRIO embedded control systems and NI CompactDAQ modular data acquisition systems. By expanding the C Series platform, NI provides engineers and scientists with new and improved options for a wide variety of embedded control, monitoring and data acquisition applications. Channel counts on the individual modules range from three to 32 channels to accommodate a wide range of system requirements, and the majority of C Series modules work in both the NI CompactDAQ and CompactRIO measurement platforms with no modification.

“We rely on National Instruments hardware and software to provide the rugged, distributed control we need for our wind turbine system,” said Jonathan C. Berg, mechanical engineer at Sandia National Laboratories. “The site-wide architecture uses NI VeriStand and the NI 9467 GPS module to choreograph all of the data acquisition and control operations.”

“This is the largest C Series module release in several years, reflecting our ongoing commitment to expanding the NI LabVIEW RIO architecture,” said Jamie Smith, director of industrial embedded marketing at National Instruments. “At NI, we constantly innovate and build upon our systems to help engineers simplify development.”

New C Series Module List

    · NI 9467 GPS synchronization module Accurately synchronize a large-scale CompactRIO system with features such as data timestamping and system clock setting.
    · NI 9469 chassis synchronization module Create high-channel-count, distributed systems with custom timing and triggering by linking chassis with a standard Ethernet cable.
    · NI 9381 multifunction I/O module Fit more functionality into a single system with analog input, analog output and digital I/O all in the same module.
    · NI 9229 and NI 9239 analog input modules with BNC connectivity Use the industry-standard BNC connection for applications such as video and RF.
    · NI 9220 analog input module with screw terminal or BNC connectivity Build high-channel-count systems in smaller chassis with 16 channels of simultaneous I/O.

Siemens introduces its versatile weighing module for Simatic control S7-1200

Siemens Industry Automation Division is launching a versatile weighing module for the Simatic S7-1200. Siwarex WP231 is the first weighing module for this control and is suitable for monitoring filling levels in silos and bins and for use with goods being weighed on platform scales. The new model is intended for industries requiring a high level of measurement accuracy, such as the food and beverage, pharmaceutical and chemical industries. Furthermore it is suitable for use in explosive atmospheres. Ethernet connections and an RS485 RTU interface with Modbus protocol enable it to be operated from a Modbus HMI panel without being connected to the Simatic S7-1200 control.

Siemens' new Siwarex WP231 weighing module can be fully integrated into the Simatic S7-1200 control, and its parameters can be quickly and easily set via the TIA Portal engineering platform. The module has four digital inputs and outputs and one analog output. The Siwarex WP231 can be connected to various systems and operator panels via an Ethernet or RS485 interface with Modbus protocol and can be operated independently from the Simatic S7-1200 ("stand-alone capability"). This makes it possible for the module to be used in various applications. In addition, the module can be operated directly from a Modbus HMI panel in the event of failure of the control unit.

Moore Industries CPT Is Both a Temperature Transmitter and a Signal Isolator/Converter

The CPT is one of the versatile products offered by Moore Industries, serving as both a PC-Programmable temperature transmitter and a signal isolator/converter. If you need to monitor temperature using a Type J Thermocouple and provide two temperature-related outputs:

- An isolated 0 to 20mA (or 4-20mA) signal corresponding to the temperature range being measured, so that all 20mA covers the full span of degrees

- A separate isolated voltage output that precisely duplicated the actual thermocouple signal in millivolts

The proposed solution to the customer’s needs involved utilizing both the HLPRG Analog (current/voltage) and TPRG Sensor (RTD/thermocouple) input models of the CPT. The TPRG input model can be programmed for a Type J Thermocouple so that a specified 0 to 20mA output covers the desired temperatures if the entire temperature span of the thermocouple is not used. This provides excellent resolution over the desired temperature range.

The HLPRG input model provides the separate isolated voltage signal. Using the input signal from the CPT TPRG model and a 0 to 10Vdc output, the HLPRG can be programmed using published “Type J to Millivolt” charts and the CPT’s “Custom Curve” feature to convert current input values to volt output values. Since the CPT outputs only 0 to 10Vdc, no minus voltages are directly available. If the desired Type J Thermocouple is measuring temperatures below freezing, the programmer needs to add an offset to bring all the output voltages above zero volts. In addition, thermocouples are always in the microvolt to millivolt range, so adding an external voltage divider can drop the CPT voltage output into millivolt levels.

Sierra introduces new Flow Meter QuadraTherm

Traditional thermal sensors have two sensors, one temperature sensor and one velocity sensor, each in a separate probe sheath.

QuadraTherm (the term “Quad” meaning “four”) introduces four sensors—three precision platinum temperature sensors and one patented DrySense mass velocity sensor. The iTherm “brain” uses these sensor inputs to calculate gas mass flow rate in a completely new and more accurate way.

Features:

  • Accuracy of +/- 0.5% of Reading
  • QuadraTherm™ Four-Input Sensor
  • DrySense™ No-Drift Velocity Sensor
  • Built-in Flow Conditioning
  • iTherm™ Proprietary Algorithm Set
  • iTherm™ Gas Property Library
  • Change Gases: Dial-A-Gas™
  • Change Pipe: Dial-A-Pipe™
  • Multivariable: T, P, Mass Flow

Ametek Drexelbrook releases Universal IV Water Cut Monitor

The new Universal IV™ CM Model Water Cut Monitor from AMETEK Drexelbrook has all of the advantages of its predecessor –the Drexelbrook CM-6 Cut Monitor--along with several key performance improvements. These include superior water cut measurement accuracy in the low ranges (0 – 1%, 0-5% and 0-10% water). Accuracy is 0.03 % water and measurement resolution is down to 0.0002 % water.

The sensing element extends a minimum of 15 inches into a main process line, taking an average of the capacitive property of the fluid over its entire length. That ensures a smoother and more accurate response, regardless of the mixture. The monitor’s onboard electronics then computes the relationship between capacitance change and water cut.

The monitor’s electronics are designed to ignore paraffin buildup on the pipe and probe. The probes are designed to handle pressures up to 1500 PSI and temperatures up to 450oF. When maintenance is required, users simply remove the probe, wipe it down and re-insert. There’s no need to take apart spool pieces or tie-off large pipelines.

The Universal IV CM can be configured for NPT or flanged mountings and can be installed in all common pipe diameters. The instrument comes pre-calibrated to one of 11 pre-set ranges, for light oil (API Gravity> 25) and heavy oil (API Gravity< 25).

The Universal IV is more compact with a smaller housing. Its proven Cote-Shield™ technology ignores coating buildup on the probe and puts the sensing area of the instrument directly into the process stream. The Universal IV also has a built-in LCD display and keypad.

The unique Perm-A-Seal sensing element on the Universal IV CM installs directly into a main process line without requiring spool pieces, side-arms or slipstreams. The sensing element utilizes a PEEK (Poly Ether Ether Keytone) material and stainless steel sensing rod that is extremely durable and requires no epoxy coatings that can wear out and require expensive servicing. There are no gaskets that require servicing, and the sensing element will not wear out in well fluids that include large amounts of sand.

All Universal IV Cut Monitors come from the factory pre-calibrated, requiring only one point validation. Field calibration can be done anywhere along the two-wire loop with Drexelbrook’s HRTwin™ PC software or via local display/keypad without a laptop or handheld communicator.
