Omnigrad - Model S TMT142R -RTD Thermometer, Fieldtransmitter Display
Safe monitoring of process temperatures in challenging applications e. g. in the Oil & Gas industry. The robust thermometer is designed for use in demanding and safety relevant applications e.g. in the Chemical, Oil & Gas and Energy industry. The thermometer fulfills the corresponding safety requirements due to various certificates and tests. The use of a transmitter leads to higher accuracy and reliability in comparison to directly wired sensors.
-
HART® protocol for operating the device on site using handheld terminal (DXR375) or remotely via the PC
-
Illuminated display, rotatable
-
Single Pt100 with 3 or 4 wires connection
-
Undervoltage detection responds immediately, output of falsified measured values is prevented
-
Highly accurate in entire operating temperature range
-
Approvals: ATEX (EEx i.a., EEx d and dust ignition-proof), CSA (IS, NI, XP and DIP)
-
Output simulation
The temperature assembly TMT142R from the Omnigrad S family is a compact resistance thermometer specifically designed to fulfill the requirements of different process industries such as the chemical, petrochemical and energy but even suitable to other general purpose applications.
The thermometer assembly TMT142R consists of a temperature RTD sensor insert (Pt100) and an electronic two-wire temperature transmitter providing a 4 to 20 mA output, configurable via HART® protocol.
