Temperature Transmitters & Controllers

Transmitters & Controllers Ensure Temperature Sensor Functionality

Temperature transmitters and temperature controllers can be seamlessly integrated with sensors to create a temperature measurement and control system for a variety of processes. Transmitters provide the capacity to send measurement information from a sensor to a monitoring location in a form that can be recognized by control equipment. Controllers take input from sensors or transmitters and translate the data into process actions that can be used to maintain or alter temperatures.

Temperature Transmitter & Controller Manufacturers

Temperature Transmitters

Temperature transmitters are used to amplify the electrical signals from temperature sensors. Transmitters allow for the measurement of temperature across distances and within processes where close proximity monitoring is challenging or impossible.

Types of Transmitters:

  • DIN Rail or Panel Mount Transmitters – mounted to a DIN rail or panel, this transmitter is ideal for centralized control and is a low cost, easy to maintain option.
  • Head Mount Transmitters – mounted directly to DIN connection heads, this transmitter is small in size, low in cost, and highly compatible with a large number of sensor types.
  • Weather Proof or Explosion Proof – providing high performance for critical applications, this transmitter is encapsulated in an explosion and weather proof compartment to ensure safety and reliability in a variety of environments.

Temperature Controllers

Temperature controllers are used to monitor and direct process temperature reactions. Controllers accept input from a temperature sensor, compare it to an identified setpoint, and provide output to a control process that will modify operations to return temperatures to the setpoint or desired range.

Types of Controllers:

  • On/Off Controller – a basic controller that directs a system to either turn on or off based on a temperature input range.  Ideal for systems that do not require a high level of precision.
  • Proportional Controller – a responsive controller that directs the system to remain within a set temperature range to prevent the cycling that is often found with the basic on/off control. The proportional controller directs the heater in a series of on and off times that are directly proportional to the temperature proximity to the setpoint.
  • PID Control (Proportional, Integral, and Derivative) – a highly sensitive controller that provides stable and accurate control through automatic compensation for any small changes in temperature.
