Temperature transmitters

High-quality temperature transmitters from WIKA

Temperature transmitters are a fundamental component in the industry. These temperature transmitter devices convert the input signal from a wide range of temperature sensors, such as resistance thermometers, thermocouples, and potentiometers, into a standardized analogue or digital output signal. The WIKA standard analogue outputs for temperature transmitters are 0…10 V or 4 … 20mA. 4…20 mA is the predominant output signal as many industries have adopted this standard for current loop communication. WIKA also offers standard digital outputs of HART, FOUNDATION™ Fieldbus protocol and PROFIBUS® PA (Process Automation).These Smart temperature transmitters are a two-way communication platform resulting in enhanced diagnostics for the device(s), free configuration of the sensor and measuring range, error signalization or measuring point identification.


What is the value of the current at the output limits in accordance with NAMUR?

Lower output limit in accordance with NAMUR is 3.8 mA (other value possible)
Upper output limit in accordance with NAMUR is 20.5 mA (other value possible)

What is galvanic isolation?

An isolation of the signal between the signal side and the output side (e.g. through coils).
