Model DP 20T and SP 20T

nnnn

Made in USA

nnnn

Overview

nnnn

The DP 20T and SP 20T Pressure Transmitters are heavy-duty, low pressure sensors for monitoring and controlling

nnnn

fabric filters, VOC abatement filters, powder processing applications, ventilation systems and any process with high

nnnn

particulate. The ability to transmit accurate measurements below 10" W.C., over a broad temperature range while

nnnn

preventing clogging, make these transmitters ideal replacements for mechanical gauges and electronic sensors that

nnnn

use small tubes that can easily clog.

nnnn

For differential measurements the flush diaphragm is mounted to the dirty or wet side of a process, such as below

nnnn

the tube sheet on a baghouse chamber or the dirty side of a wet scrubber. The reference port is routed to the clean

nnnn

side of the process. A static version is available for applications where measuring static pressure is required such

nnnn

as monitoring static pressure at a process vent hood for VFD control.

nnnn

Standard output is a 4-20mA signal for connection to a PLC, DCS or chart recorder. A remote control unit is available for

nnnn

local display, PID loop control, relay alarming and fieldbus communications. The DP 20T can also be wired directly to

nnnn

FilterSense's Baghouse Control Systems (B-PAC Controls) and IntelliPULSE timer.

nnnn

Principle of Operation

nnnn

The DP 20T employs a state-of-the-art capacitive sensing element with temperature compensation. Changes in process

nnnn

pressure or vacuum applied to the diaphragm cause deflection in the ceramic sensing element. A precise, linear 4-20mA

nnnn

output signal proportional to the pressure or vacuum is produced by the circuitry.
