Overview

Details for DM-2002-LCD

The Dwyer Instruments DM-2002-LCD is a pressure transducer designed to measure differential pressure in ranges up to 250 inches of water column (in w.c.). It features a backlit LCD display that provides easy readability in low-light conditions. The DM-2002-LCD is constructed with a rugged, weather-resistant housing that makes it suitable for use in harsh industrial environments. It also has a 4-20mA output signal that allows it to be integrated into a wide range of control systems. Some of the key applications of the DM-2002-LCD include: * Monitoring pressure in HVAC systems * Measuring pressure drop across filters * Verifying pressure in pneumatic systems * Testing pressure switches and other pressure-sensitive devices Our HVAC supply store offers the Dwyer Instruments DM-2002-LCD at the best price with fast shipping.

Series DM-2000 Differential Pressure Transmitter

Quick Response, Easy Calibration Checks

The Dwyer Series DM-2000 Differential Pressure Transmitter senses the pressure of air and compatible gases and sends a standard 4-20 mA output signal. The DM-2000 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.

Pressure connections are inherent to the glass filled plastic molded housing making installation quick and easy. Digital push-button zero and span simplify calibration over typical turn-potentiometers. An optional 3.5 digit LCD shows process and engineering units. A single push button allows field selection of 4 to 6 engineering units depending on range.

Product Applications

Filter monitoring
Fan pressure indication
Static pressures in ducts or buildings
Bi-direction ranges ideal for sensing fluctuating building pressure

Zero and span controls provide easy calibration checks and shorter installationtime to get device running and monitoring
Quick response to pressure changes means no delay in signaling and alerting tocritical situations
Easy to read LCD display provides immediate local alerts allowing corrective actionto be taken quicker to eliminate the problem from becoming widespread
Same size as Magnehelic simplifies field upgrade to digital pressure gage byreducing install steps
Tamper proof button configuration to prevent accidental changes to the settings
