![]() ![]() Because of this design, they are easy to install and require minimal wiring, as the sensor head simply becomes a sensor head transmitter. Head mount transmitters incorporate the transmitter into the connection head, or exterior housing, of a sensor. For temperature transmitters, rail mounting is the oldest mounting method. They are somewhat less accurate than weather- and explosion-proof transmitters because of the longer wiring configuration necessary for securing the transmitter. Because of the DIN rail configuration, they are also easy to install. DIN rail transmitters, also called panel mount transmitters, are usually found in diverse applications because they are relatively low-cost and can operate with an array of different sensors. The acronym DIN stands for Deutsches Institut fur Normung, which is the German Institute for Standardization. The metal rail, complete with attached transmitter, can then be attached to a panel or a wall. The rail itself is a piece of metal that is shaped to enable a device (such as a transmitter) to be attached using a spring clip, which slides into a bend in the metal rail and secures itself. Panel Mount or DIN Rail Mount TransmittersĪ DIN rail is used to mount switches, relays, and transmitters. Weather-proof and explosion-proof transmitters tend to have a high level of accuracy, and can usually be adjusted and monitored locally, if needed. Inside, the transmitter is divided into two small chambers: one contains the sensor and the other contains the electronics associated with calculating temperature and transmitting a new signal. This particular type of transmitter has an external enclosure, usually made of stainless steel or a designated explosion-proof material, which is sealed tightly to protect the sensitive internal components. In applications where a transmitter must withstand the wear and tear associated with continuous exposure to the elements, a weather- and explosion-proof transmitter is appropriate. Weather-Proof and Explosion-Proof Transmitters Panel Mount or DIN Rail Mount Transmitters.Weather-Proof and Explosion-Proof Transmitters.Some types of transmitters are named after the mounting method, meaning there is some overlap between the type and mounting method. The three general kinds of mounting set-ups include rail mounting, field mounting, and head mounting. The three general categories for temperature transmitters include weather-proof and explosion-proof transmitters, DIN rail or panel mount transmitters, and head mount transmitters. There are several different kinds of temperature transmitters as well as several types of mounting set-ups. Next, the data regarding temperature is converted into a different kind of signal and transmitted to a corresponding receiving device. In order to do this, a temperature transmitter picks up a signal generated by a temperature sensor, such as a thermocouple, and then uses the signal to calculate heat levels. Temperature transmitters are used in industrial manufacturing as a means of process control because they can provide feedback regarding temperature during different stages in the manufacturing process. ![]()
