Description
The most visible, easy to use, programmable panel meter on the market. The APM Process Meter accepts universal process inputs — 0–10V DC, 0–50mA, or 4–20mA — with 0.1% accuracy, making it suitable for variable speed drives, flow transducers, pressure sensors, and other linear or non-linear sensor measurement. 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 a monitored value is too high or too low, reducing the risk of equipment failure and improving efficiency. Free APM configuration software allows full customisation of scale, range, offset, and gain, with 16 preset configurations selectable via back-panel switches and 20-point non-linear conversion for non-linear sensors such as thermocouples and pressure transducers. It is fitted with two configurable outputs (digital open collector or analog 4–20mA), 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 variable speed drives, flow transducers, pressure sensors, and other linear or non-linear process sensor measurement.
