The popular VA710 temperature calibrator performs two functions for the 9 most common thermocouple types. In Input Mode, it accurately measures the milliVolt signals produced by thermocouple sensors and probes and displays them as a temperature. In Output Mode, you set the required temperature and it accurately generates its own milliVolt signal to simulate a thermocouple signal to an instrument (such as a digital thermometer, chart recorder, temperature controller, PLC, etc).
Should you need better accuracy, we also offer the EzzyCal – 2750 Thermocouple Calibrator which is designed for AMS 2750 aerospace spec applications.
The VA720 Pt100 simulator performs measure and source functions for resistance temperature detectors (RTDs), covering 7 types, including Pt100 and Pt1000, in 4-wire, 3-wire and 2-wire configuration. Like the VA710 does for thermocouples, it can accurately measure Pt100 probes and also inject electrical signals into most types of instruments to simulate a Pt100 signal.
The VA700 is a Current and Voltage process calibrator for various industrial sensors, transmitters and instruments. It measures and simulates 0-24mA signals for current loops, either as milliAmp values or as a percentage of the 4 to 20mA range. It also measures and simulates 0-15 volts (dc). For current, it works with externally powered loops or provides its own 24V loop power. Measurements using these types of signal include, contact temperature (via transmitters for thermocouples & Pt100s), infrared non-contact temperature, pressure, humidity, flow, level and many more.
These instruments are very useful tools for calibrating, checking accuracy or fault-finding temperature and process equipment in many industrial applications. An optional mains power supply adaptor is available, which may prove helpful for use in a lab or workshop. We can also offer calibration of your existing calibration and test equipment in our UKAS accredited calibration lab.
