Description

The FST800-1000 pressure transmitter utilizes a high-stability ceramic capacitive sensing element housed within a fully welded 304 stainless steel chamber, ensuring leak-proof operation and resistance to harsh media. Its integrated digital signal conditioning circuitry provides automatic compensation for temperature effects, minimizing zero and full-scale drift across the specified -40°C to +85°C medium temperature range.

Designed for industrial environments, the transmitter features built-in protection against RF/EMI interference, surge events, and reverse polarity. The 4-20mA output provides a linear, proportional representation of the applied gauge pressure, suitable for direct connection to standard process control instrumentation.

Key Features

Industrial-grade 4-20mA two-wire transmitter with 1% FS accuracy.
Robust all-stainless-steel (304) and ceramic construction for long service life.
Advanced digital temperature compensation (±0.02%FS/°C drift).
High resistance to RFI/EMI, surge, vibration, and corrosion.
Laser-welded pressure chamber ensures a safe, leak-free seal.
Wide compatible media temperature range from -40°C to +85°C.
Reverse polarity and lightning protection circuitry integrated.
G1/4 male thread pressure port for standard industrial piping.

Applications

Industrial hydraulic and pneumatic system pressure monitoring and control.
Oil and lubricant pressure sensing in machinery and pumping stations.
Process pressure measurement in water treatment and filtration systems.
Pressure feedback for automated industrial machinery and robotic systems.
Condition monitoring in pump, compressor, and valve control loops.

Frequently Asked Questions

What is the wiring configuration for the 4-20mA output on this transmitter?

The FST800-1000 is a standard two-wire transmitter. You connect the positive supply voltage (9-30V DC) to the positive terminal, and the 4-20mA output signal is drawn from the negative terminal, which is connected to your PLC or receiver's analog input. The loop power and signal share the same two wires.

Is this sensor suitable for measuring oil pressure directly?

Yes, the all-stainless-steel (304) construction and ceramic sensing element provide excellent corrosion resistance and compatibility with a wide range of media, including oils, hydraulic fluids, and water. The G1/4 male port is a standard fitting for such applications.

What is the meaning of the accuracy specification '1% FS'?

'1% FS' stands for 1% of Full Scale. For this 0-25 bar sensor, the maximum error across the entire range is ±0.25 bar. This includes the combined effects of non-linearity, hysteresis, and repeatability at a reference temperature, typically 25°C.

Does the sensor require an external signal conditioner?

No, the transmitter has a fully integrated signal conditioning circuit. It directly outputs a standard 4-20mA current signal proportional to the applied pressure. You only need to provide a DC power supply within the 9-30V range and connect it to a current-reading input on your controller.
