APM Panel Meter 4-20mA
Product Range
APM-PROC-APO Panel Meter
Digital Panel Meters TRUAPM for 4-20mA, 0-10V input signals
The Trumeter APM-PROC-APO features a highly visual, easy to read, display and a versatile range of analogue inputs, this Process Meter takes APM into a
wide range of new industrial applications.
The user programmable scale and customized annunciators allow users to specificaly tailor the meter to display their critical parameters exactly
to what they want, whilst the dynamic back-lighting, combined with set points, means users are instantly, visually alerted when the
measured input is out of range. The two outputs can be used to integrate into other systems, such as SCADA and BMS.
Innovative design technology brings a greater level of accuracy to the APM range through input signal optimization. An accuracy of 0.1% or better can now be achieved, allowing for more precise measurement, digital display and control.
Non-linear sensors, from devices such as pressure transducers, can also be used thanks to the new APM Configurator
application that allows the user to configure upto 20 points in a non linear conversion table.
APM-PROC-APO Applications
The APM Process digital panel meter is used to display the volume of liquid in the tank. The 4-20mA analog output from the liquid level sensor is scaled to gallons, and the custom annunciator set to "Gal", all via the easy-touse software application. High and low setpoints are configured so that the normal green display will flash red when the tank is too full or empty, alerting the operator. Additionally the APM digital outputs are integrated into the tank pumping system and the tank is automatically drained or filled if the setpoints are exceeded.
The APM-PROC-APO Process Meter is used to provide digital display of the material volume in the
silo, using the analogue output from a
level sensor.
The signal from the sensor is scaled into
the measurement units cubic metres,
and the annunciator customised to m3
, all
via the easy-to-use software. Due to the
irregular shape of this silo, the 20-point
non linear table is used to correct the
non-linear signal from the sensor.
The displayed value accurately shows
the volume in the silo. High or low
setpoints can be set, and the APM
can be integrated into other systems
for process control.
