Description
The most visible, easy to use, programmable panel meter on the market. The APM Temperature Meter accepts Type B, E, J, K, N, R, S and T thermocouples, with innovative input signal optimisation delivering accuracy to within 0.5°C after 30 minutes and 0.2°C after 40 minutes. It combines the instant readability of an analog meter with the precision of a digital meter: a 40-segment curved bar graph gives an immediate visual indication, while four 12mm digits provide a precise numeric readout.
This variant uses a negative (dark-background) LCD, giving strong contrast in normal indoor and panel-mounted lighting conditions.
The colour-changing backlight can be programmed to alert operators when temperature is too high or too low, reducing the risk of process upset or equipment damage. Free APM configuration software allows full customisation of scale and range, with 16 preset configurations selectable via back-panel switches and a configurable 20-point non-linear conversion table for accurate readings across the sensor’s full range. It provides a 4–20mA analog retransmission output alongside a second configurable digital or analog output, supporting up to 10 independent alarm setpoints with a configurable digital output delay (0.5–120 seconds). Optional Modbus RTU communication and remote monitoring via Trumeter Cloud and the APM Gateway are also supported.
Typical applications include HVAC systems, industrial ovens, and other temperature-critical process control where accurate, at-a-glance thermocouple monitoring is needed.
