OPTITEMP TT 12 R with RTD input
The OPTITEMP TT 12 R is a universal programmable 2-wire rail-mounted temperature transmitter for Pt100 and Pt1000 RTD elements or thermocouple (TC) elements. The cost-effective transmitter offers reliable temperature measurement in all basic applications and is particularly suitable for use in the food and beverage industry and in HVAC installations. The OPTITEMP TT 12 R features an extremely compact design with a 6.5 mm width. There are different snap-in terminals available for the OPTITEMP TT 12 R that allow ease of installation. Thanks to its rugged design, the temperature transmitter withstands external influences such as shocks and vibrations up to 5 g.
When it comes to transmitter configuration, there is no need for expensive configuration tools or wired workstations. The rail-mounted transmitter is easily configured via NFC with any smartphone or tablet computer using the OPTICHECK Temperature Mobile app. The temperature transmitter provides a temperature linear current output (4…20 mA). A dedicated head-mounted version of the transmitter is available with the OPTITEMP TT 12 C.
Product highlights
- Very small form factor: Only 6.5 mm width for space-saving installation on all rails
