1. INTRODUCTION
The PT-FD series of transmitters features, a flush diaphragm process connection.
They are specifically designed for the measurement of viscous fluids or media containing
solids that may clog a process connection. Flush diaphragm pressure transmitters are
available in pressure ranges as low as 1500INWC.
The flush diaphragm could be easily flushed or cleaned to remove dirt. The model
offers reliable and accurate pressure measurement of the gases, viscous liquids and
slurries. And for the electrical parts adopt high performance chips, and deal with special
amplified chip, integrated configuration, and smart profile. A wide range of electrical
connection and process connection options are available to meet almost any requirement.
2. PRESENTATION
2.1 Features
1. Improved media compatibility.
2. Excellent resistance to corrosive processes.
3. Compact Design and Rugged construction.
4. Wide range of available process connections and signal outputs.
5. OEM process to fit application of the customers.
6. Resistant to pressure spikes and vibrations.
7. Stainless steel case and wetted parts
8. Can be assembled to diaphragm seals for special applications.

6. INSTALLATION
Recommendation
1. Please confirm the configuration for Pressure Transmitter i.e. 2- wire, 3-wire and accordingly follow the
wiring procedure. Ensure that the excitation voltage is supplied to the correct points and is with in the
specified limits for that particular configuration as mentioned in the table above.
2. When installed, ensure that the transmitter is not subjected to the excessive sources, and it should be
considered before installing the Transmitter. Use suitable diaphragm if needed.
3. Process connection must be properly sealed with material compatible with the process liquid / gas.
4. When installing transmitter with diaphragm, seals / process connector should be tightened not the
transmitter, otherwise transmitter calibration may get affected.
