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.
