Overview

The Series DM Digimag® Differential Pressure Transmitter senses the pressure of air and compatible gases and sends a standard 4-20 mA output signal. The DM housing is specifically designed to mount in the same diameter cutout as a standard Magnehelic® gage. A wide range of models are available factory calibrated to specific ranges. The polycarbonate molded housing features integral pressure connections, which reduces installation time. Digital push-button zero and span simplify calibration over typical turn-potentiometers. A single push-button allows field selection of 4 to 6 engineering units, depending on the range.

Product Applications

Differential pressure across filters
Fan control
Static pressures in ducts or buildings
Room pressurization monitoring

Features

Display Units: psi, kg/cm², bar, in Hg, ft w.c., kPa, MPa, %FS, in w.c., mbar, cm w.c., mm Hg, or oz/in² (choices depend on range).
Test Mode:Simulates input over the range without pressuring to easily test switches and transmitter output feature.
Fail-safe: For sensor failure, over pressure, high temperature limit, low temperature limit, or keypad short. User chooses if relay is de-energized, energized, or no action. With transmitter option, user chooses an output of 3.6 mA 22 mA, or no action.
Alternation: Selectable alternation of set points between the relays for even wear on duplex pump applications.
Versatile Compact Package: Can replace a separate gage, two switches, and a transmitter in a system saving, money, installation time, and panel space.
Fully Programmable:To meet simple or complex application needs.
Weatherproof Housing: Ideal for a wide variety of applications with panel mount, flush mount, or pipe mount ability.
