ST 2500 HART Pressure Transmitters The Economical Pressure Solution with HART Communication The Honeywell ST 2500 HART Pressure Transmitter is designed to provide reliable pressure measurement for a wide variety of applications. The transmitter measures and indicates gauge or absolute pressure with ranges from 0 to 350 bar (0 to 5000 psi) gauge pressure and 0 to 35 bar (0 to 500 psi) absolute pressure. Digital communication is easily implemented using standard HART protocol communication. ST 2500 Pressure Transmitter Features and Benefits ST 2500 Family The ST 2500 family includes ten gauge pressure models. All models have a turndown capability of up to 10:1. A piezo-resistive semiconductor sensor and microprocessorbased electronics combine to provide a two-wire 4-20mA output signal that is proportional to the measured variable. The microprocessor enhances accuracy by compensating the signal for temperature effects of the sensor. Easy-to-Read LCD Display The ST 2500’s built-in, easy-to-read LCD display indicates measured pressure in engineering units or percentage and also displays the temperature of the sensor. The user can configure the transmitter with the aid of the 2-line, 16-character LCD indicator and four pushbuttons, or digitally using a HART protocol hand-held communicator. • Accuracy = 0.15% to 0.10% FS • 0 to 350 bar (0 to 5000 psi) gauge pressure • 0 to 35 bar (0 to 500 psia) absolute pressure • Piezo-resistive semiconductor sensor • Temperature compensated for enhanced accuracy • Easy configuration via large LCD indicator and four pushbuttons • HART communication • Intrinsically safe • Compact and light weight ST 2500 Replaces Conventional Analog Transmitters and Indicators The ST 2500 Pressure Transmitter is designed as a direct replacement for conventional analog transmitters and indicators. It uses the existing transmitter signal lines for power, signal transmission, and HART communication. ST 2500 is Versatile Several process connections are available for the ST 2500. These include 0.25 inch or 0.5 inch NPT and a 1.5 inch or 2 inch Tri-clamp for sanitary applications.
