TMT31-AAA1A1A1B2C1PA

TMT31-AAA1A1A1B2C1PA is an iTEMP TMT31 series, temperature transmitter. It is characterized by its reliability, long-term stability, high precision and diagnostic functions. It is a reliable, long-term stable, single-channel 4 to 20mA temperature transmitter for thermometers with terminal head Form B suited for use in Zone 2 / Div. 2 areas. Individual transmitter-sensor matching with Calendar-Van Dusen linearization further improves your temperature measurement accuracy for RTD sensors. Push-in terminals for quick wiring facilitate installation. The device is available for pre-configured or can easily be parametrized using free software tools. It is certified by ATEX II3G Ex ec IIC Gc, CSA C/US general purpose, CSA C/US NI Cl.I Div.2 Gr.A-D,Ex ec IIC Gc, ATEX II3G Ex ec IIC Gc + CSA C/US Ex ec IIC Gc, DNV (GL) marine approval.
