Temperature is one of the most measured parameters in industrial applications and is highly important to the smooth running of many different kinds of processes. A temperature transmitter is an electrical instrument that interfaces with a temperature sensor to measure or control a process. These devices offer a wide measuring range, good accuracy and a simple yet reliable design. At BM Engineering Supplies we offer a wide range of temperature transmitters, including A comprehensive selection of Bürkert temperature transmitters.
How a temperature transmitter works
Typically, temperature transmitters work by isolating, amplifying, linearising and converting the input signal from a sensor. The temperature transmitter then transmits a standardised output signal to a 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. To find out more about how a temperature transmitter works take a look at our helpful blog ‘What is a temperature transmitter?’
Temperature transmitter types
At BM Engineering, we offer a huge array of temperature transmitter types, including a selection of Bürkert temperature transmitters. With more than 40 years of industry experience, we can assist you with the purchase of your next temperature transmitter and can help you find the ideal product for your application. Below is an example of the type of temperature transmitters we can offer.
Bürkert type 8400 temperature transmitter
Bürkert’s Type 8400 temperature transmitter is an intelligent sensor/switch with an extra-large display. It is specifically designed to switch a valve and to establish a monitoring system or an ON/OFF control loop. Compact and wall versions are available and connections to the process in the piping are made using standard fittings.
The switching points can be programmed with the three keypads or optionally, with input 4 – 20 mA from an external PLC over a 4 – 20 mA loop. The process value can additionally be transmitted to the PLC (4 – 20 mA). This device also delivers menu-guided parametrisation and complete communication thanks to external set points.

Output limits are signal limits. In other words, where your signal should be measured up to.
At BME, we recommend a digital temperature transmitter because with digital you only have to measure once. The measurement is immediately converted to a digital ‘word’ for further processing. On the other hand, with analogue you must re-measure at each step in the process, which leaves more room for error.
