Process calibrators measure and generate diverse process variables. These portable and extremely handy instruments are ideal for on-site use. In addition to electrical signals such as current, voltage and resistance, further variables such as temperature, pressure and frequency can be measured and additionally generated. The implemented sensor functions simulate specific supply variables and display an exact given value. This distinguishes a signal calibrator from the conventional measuring functions of a multimeter. The documentation of calibration results is also actively supported with internal memory and display functions or convenient external control via PC software. The combination of different types of signals determines the Process calibrator type and its specific features. Whereas monofunction Process calibrators can only process one type of signal, multifunction Process calibrators can process different types of signals. Available are resistance thermometers (RTD) and thermocouples (TC) with varying linearisation and corresponding resistance (Ω) and voltage signals (mV). Analogue current (mA) and voltage signals (V) as well as frequency (Hz) and pulse signals (O / C) and pressure signals (bar) round off the spectrum.

Monofunction process calibrators
SIKA monofunction process calibrators offer exceptional performance, durability and reliability. Our temperature or current loop calibrators are compact, lightweight and easy to transport. These instruments feature rubber keys for ease of use and are insensitive to dust and splashing water. The tough plastic housing is resistant to shocks and impacts and offers additional protection against vibrations in harsh environments. Screened 4 mm sockets allow quick and easy connection of equipment to be tested.

Multifunction process calibrators
SIKA multifunction process calibrators combine the functions of several devices in one instrument. These process calibrators are designed for easy generation and measurement of temperature, pressure, frequency and electrical signals. These documenting instruments have been developed for testing and calibration of numerous process signals as well as their generation and measurement with high accuracy. Operation is intuitive via keypad or pull-down menus.
