Micaflex PU3 Purging unit for MFS flow sensor MICATRONE VIỆT NAM

Description

Micaflex PU3 is designed to be used with Micatrone transmitter type Micaflex PFTT or PFA-PU to prevent a connected flow sensor or pressure tap from clogging in applications where the measured air flow is poluted or an increased risc of condensation is present.
The transmitter control the purging units solenoid valves. The purging interval can be set between 30 and 3600 seconds and every purging period can be set between 0 and 60 seconds. During purging, the output signal from the transmitter is frozen to avoid interference in the measurement.
PU3 consists of two solenoid valves that are controlled with a built-in relay. The relay is controlled using a 12…15 VDC control signal from the transmitter. All pressure connections are made on the outside of the enclosure.

Technical Data

During the pause period, the flow sensor or pressure tap is connected to the PFTT/PFA-PU.
During the purging period, two valves inside the unit close the connetion to the PFTT/PFA-PU and opens the connection for the compressed air inlet to clean the flowsensor or pressure tap.
