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.

FAQ

What is the difference between analogue and digital transmitters?

At WIKA, analogue transmitters have analogue electronics fitted but no processors.
Digital transmitters have processors. The output signal can, however, be a 4 ... 20 mA analogue signal for both types.

What does „Pt100“ mean?

A platinum resistance temperature detector (RTD); Pt100 is a device with a resistance of 100 Ohms at 0°C . Its resistance changes as its temperature changes. The resistance is proportional to the temperature of the RTD. Pt stands for Platinum with a nominal res ... More
