Frequency Meter

The Trumeter APM Frequency Meter is a programmable digital frequency meter for effective monitoring, measuring and displaying of AC or DC Frequency.

Frequency Meter APM Features

Digital Frequency Meter

The APM Frequency Meter has an input range of 2-400Hz and an accuracy of 0.1%. It is the only digital frequency meter that features dynamic backlight that can be tailored to alert the user whenever a critical parameter is out of set range. The display can be set to flash and/or change color (or intensity) between red, green and white.

Frequency Meter APM Backlight Color Change

This provides an immediate visual indication of critical parameters and clear accurate readings, improving performance monitoring as well as safety.

 

Programmable Frequency Meter

The APM is a programmable frequency meter that is easily customized to your requirements via the configuration software. Alternatively you can use one of the 15 pre-loaded configurations. The 40-segment bar graph can be programmed to the scale you require, while the positive and negative and centre zero scales can also be configured. It can also be configured to accurately measure DC pulses.

The APM’s unique LCD display incorporates the instant recognition of traditional analog frequency meters with the precision and accuracy of digital panel meters, making it the ideal meter for a range of frequency measuring applications including:

– AC mains applications

– generators and power performance monitoring

– industrial applications

– process monitoring

– aviation industry applications

 

APM Frequency Meter Options

The Frequency Meter is available with analog and digital outputs so the panel meter can interface with other systems, including generators, beacons, sounders, or other indicators, for even clearer notification of frequency, and with either a positive or negative LCD.
