Self-calibrating RTD for biopharma

Endress hauser itherm trustsensiTherm TrustSens hygienic RTD is reported to be the world’s first self-calibrating temperature sensor, functions in situ, and calibrates after every sterilization in place (SIP) cycle, which eliminates the risk of undetected drift. TrustSens has a built-in, high-precision ceramic reference based on the Curie Point of the reference material. TrustSens measures temperatures from -40 °C to 160 °C (-40 °F to 320 °F), works in pressures up to 725 psi, and provides a 4-20 mA output with HART. It also has hygienic process connections.


Low cost, 32 signals, one twisted pair

moore temperature concentrator systemTemperature Concentrator System (TCS) concentrates as many as 32 signals on one twisted pair, which delivers precision measurements at less than 25% the cost of comparable smart transmitters. TCS accepts any combination of RTD, T/C, mV and resistance/potentiometer inputs, and converts inputs to HART. At less than 5 in. wide, each loop-powered TCS module handles 16 measurements, and can communicate via Modbus RTU with an optional HART-to- Modbus converter (HMC) module.

Thermowell reduces fatigue failure

emerson rosemount twisted square thermowellsRosemount Twisted Square thermowells dampen dynamic stress from oscillating vortex pressures that can result in vortex-induced vibration (VIV) and thermowell failure, and are reported to reduce VIV by more than 90%. They simplify process calculations by eliminating the need to size thermowells, and provide more accurate temperature measurements. They're suitable for use where conventional thermowells fail to meet the ASME PTC 19.3 TW standard for safe and reliable thermowell design.

Up to 1,000 bar and 135 °C

turck pt2000 pressure transmittersPT2000 pressure transmitters have a welded, stainless-steel measuring cell, no elastomer seals, and 316L stainless-steel wetted materials. The compact transmitter housing is gel-filled, eliminating problems caused by condensation. PT2000 can handle pressures up to 1,000 bar and process media up to 135 °C. PT2000 offers multiple output signals including 4-20 mA, 0-10 V, ratiometric, 1-6 V and 0-5 V. It's also IP67-rated, and has an operating range of -40 to 135 °C.


Time-saving temperature calibration 

ametek jofra ctc 1205 temp calibratorJofra CTC-1205 compact temperature calibrator offers a temperature range of 100 °C to 1,205 °C (212 °F to 2,201 °F), accuracy of ±0.2 °C (±0.36 °F), and stability of ±0.1 °C (± 0.18 °F) for the total temperature range. It offers silent-mode operation; faster cooling times—down to just 45 minutes; and mains power variance immunity (MVI) circuitry for stability. CTC-1205 also has an intuitive interface, automatic switch test and auto stepping, and is available with special one-key-one-function buttons.

Loop-powered, dual-temperature with HART

phoenix contact macx mcr ts i olp temp transmitterMACX MCR-TS-I-OLP loop-powered, dual-sensor temperature transmitter supports more than 28 different temperature sensors. The module also accepts -20 mV to 100 mV and linear resistance ranges from 10 ohms to 2,000 ohms. On the output side, it features a dedicated 4-20 mA signal with HART. At only 12.5 mm wide on a DIN rail, MACX MCR-TSI-OLP is thin, but the wide operating temperature range of -40 °C to 85 °C makes it widely usable. Approvals include ATEX, CSA, FM, EAC and UL Class I, Div. 2.
