Description
Fischer DE50 – Smart DP Transmitter Switch – rugged, microcontroller based
smart differential pressure transmitter with limit switch, high accuracy, with LED display, microcontroller based
Make: Fischer Messtechnik (Germany)
Model: DE50
Fischer DE50 multi-functional, high accuracy, rugged industrial smart differential pressure transmitter. It is suitable for over pressure, vacuum gauge and differential pressure monitoring for air and gaseous media.
DE50 comes with large onboard LCD display, limit switch / contacts and analog voltage or current transmission output.
Working Principle:
DE50 is based on capsule element measuring system suitable for overpressure, vacuum and differential pressure measurement. Pressure to be measured displaces the capsule element and moves the core of inductive displacement transducer.
The electronic amplifier generates an electrical output signal, which can transmitted as voltage or current.
Flow rate and volume of gaseous media can be measured by measuring differential pressure via square-root extracted signal output. For these applications, transformation electronics are used which supply square-root extracted output signals.
DE50 also equipped with onboard LCD display for measured values indication, and with adjustable potential free relay output or limit switches for control function.
