M30/40 and T30/40 Series

Differential Pressure Transmitters

Order Now Order Now!
Modus M30/40 and T30/40 Series Differential Pressure Transmitters are reliable, stable, low-air pressure transmitters with 4-20 mA outputs. The M30 and T30 Series are DC-powered, while the M40 and T40 Series are AC-powered. Ranges up to 2" W.C. utilize a differential capacitance cell for pressure measurement. Higher ranges utilize piezo-resistive sensors. Ranges are available from 0" to 0.3" W.C. to 0" to 10" W.C. All models may be furnished in bidirectional ranges, which will measure both positive and negative pressure differentials. Models M30 and M40 are for NEMA 4 applications or applications that require CE-approved products.

One of the M30's I got had the high and low ports switched internally. I have sent it back. Several did not seem to respond properly. This caused the commissioning crew to loose confidence in the units. This was a Corps of Engr. bldg. and a "Leed" project for a Fort Sam Houston headquarters bldg.
No, I do not recommend this product.
