TMT162 Technical data
Endress+Hauser 43
10.0.2 Output
Output signal Analog 4 to 20 mA, 20 to 4 mA
Signal on alarm Breakdown information to NAMUR NE 43
Breakdown information is created when the measuring information is invalid or not present
anymore and gives a complete listing of all errors occuring in the measuring system.
The high alarm is adjustable between 21.6 mA and 23 mA allowing for flexibility when working
with the requirements of most control systems.

1) High measuring error increase for temperature lower than 572 °F (300 °C).
2) When operating conditions are based over a large temperature range, the TMT162 offers you the ability to do a split range. For example a Type S or R thermo-
couple can be used for the low range and a Type B can be used for the upper range. The TMT162 is then programmed by the end user to switch at a prede-
termined temperature. This allows for utilization of the best performance from each individual thermocouple and provides 1 output that represents the process
temperature. Note the dual sensor option must be requested when placing an order.
3) Basic requirements NE 89:
Detection of increased wire resistance (e.g. corrosion of contacts or wires) of TC or RTD/4-wire. Warning - exceeding ambient temperature.
