| Product Type | Pressure Transmitter |
| Pressure | > 1 in. 6 PSI/ < 1 in. 3.6 PSI |
The Dwyer series DM DigiMag® differential pressure transmitter sensed the pressure of the air and compatible gases, it sends a standard 4-20mA output signal. The housing on the DM series is designed to mount in the same diameter cutout as a standard Magnehelic® gauge. It features integral pressure connection, which reduces installation time. Digital push-button zero and span provide easy calibration. A single push-button allows field selection of 4 to 6 engineering units, depending on the range. Features Reduces installation time with zero and span controls that provide quick & easy calibration Immediate corrective action can be taken on local alerts with the easy to read LCD display Reduces upgrade installation costs and simplifies upgrade from a Magnehelic® gauge due to both have the same diameter cutout Applications Filter monitoring Fan control Static pressure in ducts and buildings Room pressure monitoring Specifications Service: Air and non-combustible gases (compatible) Accuracy: ±1% FSO for ranges < 0.25 in. w.c. = ±2% FSO & ranges at/below 0.1 in. w.c.= ± 4 5 FSO Temperature: -4 to 158° F (-20 to 70° C) Thermal effect: 0.025 FS/°F (0.036% FS/°C) Pressure Limits: Ranges >1 in. w.c. = 6 PSI max operation & burst/ ranges, < 1 in. w.c. 3.6 PSI max operation & 6 PSI burst Power requirement: 10-35 V DC (2-wire) Output signal: 4-20 mA (2-wire) Electrical connections: Screw type terminals Process connections: Male ports on side for 1/8', 3/16" or 1/4" ( 5 mm or 6 mm) ID flexible tubing Mounting orientation: NEMA 4X ( IP66) Push -button zero and span adjustments 0 to 1250 ohms max. 21 mA max. current consumption Housing: Polycarbonate Size: 5 in.
