1) Significant measuring error increase for temperature lower than 300 °C (572 °F).
2) When operating conditions are based on a large temperature range, the TMT162 offers the ability to split the range. For example, a Type S or R thermocouple
can be used for the low range and a Type B can be used for the upper range. The TMT162 is then programmed to switch at a predetermined 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 included in the order code for the HART
®
protocol. Two sensor inputs are already provided as standard if the FF and PA
protocol are selected.
3) Basic requirements NE89: detection of increased sensor resistance (e.g. corrosion of contacts or wires) of TC or RTD/4-wire.
