Ecogate Power MASTER VFD Update

Updated: Mar 8, 2022

The pressure transmitters for measuring the Fan Total Pressure and Filter Differential Pressure are prewired and built-in with the Power MASTER with all software parameters already set for a faster and more convenient installation. The installer needs to only bring hoses from the fan inlet and outlet pressure taps, and the filter inlet and outlet. These hoses can be as long as necessary without affecting the measurement precision.

Ashcroft CXLdp Pressure Transmitter

Ecogate has updated both the filter and fan pressure transmitters to Ashcroft CXLdp with 0.8% precision, 4-20mA output, and ¼” brass barbed male fitting.

Ecogate chose Ashcroft transmitters for their TruAccuracy™, good overpressure protection, and superior long-term stability. Another advantage is that the same sensor is available for a wide range of differential pressures.

For the differential filter pressure of the dust collector, we are using CXLdp with a pressure range of 10” w.c. This improves filter pressure precision over the previously used transmitters with 25” w.c. range. A properly cleaned dust collector filter should have differential pressure about 2”w.c. or less, dirty filter 5” w.c. or less. If your filter pressure is over 5” w.c., you should troubleshoot with the filter manufacturer.

The fan pressure transmitters for the Power MASTER units up to 200 HP are now using 25” w.c. differential pressure sensors. These are wall-mounted units.

The Power MASTER VFD 250 HP and over (250, 300, 350, 400, 450 HP) are used for larger industrial applications where fan pressure can be over 25 w.c., therefore we are using 50” w.c. pressure transmitter. These are standalone units.

By special order, we can produce Power MASTER units with different pressure transmitter ranges (from 0.1 to 100 “ w.c.). For example for vacuum systems, we are using pressure transmitters with 100” w.c. range (7.4 “ Hg).

Ecogate Power MASTER VFD delivers many benefits to those who use them:
