Temperature Transmitter

Featured Product from KROHNE Messtechnik


The OPTITEMP TT 53 C is a universal, programmable, 2-wire head-mounted temperature transmitter. The galvanically isolated transmitter works with RTD elements, thermocouple (TC) elements or other inputs (mV and Ω). It supports wireless Near Field Communication (NFC) as well as Bluetooth® communication. The OPTITEMP TT 53 C transmitter can thus be remotely configured and monitored using mobile devices.

Featuring HART®7 communication, the transmitter also offers extended diagnostic information (for example device error, sensor and wiring conditions). In addition, it is able to measure the actual supply voltage as well as the ambient temperature while making them available via HART®. The maximum values are stored internally. The robust design of the OPTITEMP TT 53 C makes the transmitter highly reliable even under harsh environmental conditions. The temperature transmitter is available for use in hazardous areas. It is designed to be mounted in a "B connection head". A dedicated rail-mounted version for DIN rails is available with the OPTITEMP TT 53 R.
