KROHNE, Inc. highlights the OPTITEMP TT 53, a universal programmable 2-wire temperature transmitter for resistance (RTD) and thermocouple (TC) elements. Aimed at the Chemical, Oil & Gas and the Power Generation industries, it features HART® 7 communication, NAMUR NE 107 diagnostics as well as Ex approvals.

Available in both compact (C) and rail-mounted (R) versions, the new transmitter can be programmed via PC or HART handheld, or wireless by using the OPTICHECK Temperature Mobile app for iOS and Android devices. The app can communicate with OPTITEMP TT 53 via the built-in Near Field Communication (NFC) or the optional OPTITEMP TT-CON BT configuration kit, a small Bluetooth modem. From a mobile device, the user can program, configure and monitor the transmitter, e.g. set mA outputs, perform an output simulation, view actual supply voltage, check the runtime counter and the current or historical process/ambient temperature log. Via HART 7 communication, some of these readings can also be made available to a control system.

The robust design of the OPTITEMP TT 53 ensures reliable operation even under harsh environmental conditions: vibration-resistance up to 10 g, a fast step response time and a high accuracy (±0.08% of span; max. ±0.08 ˚C) result in a high long-term stability (max. drift ±0.02% of span/year). The transmitter is suitable for use in ATEX and IECEx rated hazardous areas. OPTITEMP TT 53 offers extended diagnostic information according to NAMUR NE 107, e.g. device error, sensor break monitoring and wiring conditions. It is also compliant to NAMUR recommendations NE 21, 43 and 53.
