Temperature Transmitters for Signal Conditioning
Temperature transmitters convert thermocouple, RTD, and low-level temperature sensor signals to 4-20mA, 0-10V, or other DC voltage/current outputs. Acromag offers temperature transmitters in head-mount and DIN-rail form factors. Some temperature transmitters have software-configured universal input to convert a broad range of temperature sensor and other signals with a single unit. Many options to choose from -Â head mount temperature transmitter, DIN-rail temperature transmitter, universal programmable transmitter browse the options below.Showing all 15 results

What is a Temperature Transmitter For Signal Conditioning?
A temperature transmitter is an electrical instrument that interfaces a temperature sensor for example a thermocouple, RTD, or thermistor sensor to a measurement or control device like a PLC, DCS, PC, loop controller, data logger, display, recorder, etc.
Typically, temperature transmitters isolate, amplify, filter noise, linearize, and convert the input signal from the sensor then send or transmit a standardized output signal to the control device. Common electrical output signals used in manufacturing plants are 4-20mA or 0-10V DC ranges. For example, 4mA could represent 0°C and 20mA means 100°C.Â
Temperature Transmitter Inputs
A thermocouple sensor is a pair of dissimilar metal wires joined at one end. The junction produces a low level voltage proportional to the difference in temperature between the open and closed ends.
An RTD or Resistance Temperature Detector is a passive circuit element whose resistance increases with increasing temperature in a predictable manner.
