## Overview

The Mercoid Process Differential Pressure Transmitter, model 3100D-7-FM-1-1-LCD, is an explosion-proof device designed for high accuracy and versatile applications. With a pressure range of 0 to 1000 psi, it features configurable settings, auto temperature compensation, and EEPROM-saved configurations for reliable performance in demanding environments.

## Description

The Mercoid Series 3100D Smart Pressure Transmitter is a microprocessor-based high performance transmitter, which has flexible pressure calibration, push button configuration, and programmable using HART Communication. The Series 3100D is capable of being configured for differential pressure or level applications with the zero and span buttons. A field calibrator is not required for configuration. The transmitter software compensates for thermal effects, improving performance. EEPROM stores configuration settings and stores sensor correction coefficients in the event of shutdowns or power loss. The Series 3100D is FM or ATEX approved for use in hazardous (classified) locations. The 100:1 rangeability allows the smart transmitter to be configured to fit any application. Service: Compatible gases, steam, liquids or vapors. Wetted Materials: 316L SS. Accuracy: ±0.075% FS (@ 20°C). Rangeability: 100:1 turn down. Stability: ±0.125% FSO/yr. Temperature Limits: Process: -40 to 248°F (-40 to 120°C); Ambient (without LCD): -40 to 185°F (-40 to 85°C); Ambient (with LCD): -22 to 176°F (-30 to 80°C). Pressure Limits: Max. pressure: Range: -14.5 to 2000 psi; Burst pressure: 10000 psi. Thermal Effect: ±0.125% span/32°C. Power Requirements: 11.9 to 45 VDC. Output Signal: 4 to 20 mA/HART Communication. Response Time: 0.12 seconds. Damping Time: 0.25-60 seconds. Loop Resistance: Operation: 0 to 1500 Ohm; HART Communication: 250 to 500 Ohm. Electrical Connection: Two 1/2" female NPT conduit, screw terminal. Process Connection: 1/4" female NPT. Display: Optional 5 digit LCD. Enclosure Rating: NEMA 4X (IP66) and explosion-proof for Class I, Div I, Groups A, B, C and D. Weight: 8.6 lb (3.9 kg). Agency Approvals: CE, FM, ATEX option available (consult factory).
