Description

The FST800-4001 pressure transmitter employs an advanced glass micro-melting process, where the sensing element is sintered at high temperatures to create a monolithic, leak-free elastomer structure. This design eliminates O-rings and weld seams, significantly enhancing corrosion resistance and long-term seal integrity under high-pressure hydraulic fluids and gases. The integrated intelligent digital compensation circuitry actively corrects for temperature effects across the operating range of -10°C to +70°C, maintaining high accuracy and stability.

Built for industrial durability, the sensor withstands significant shock, vibration, and overpressure conditions. Its stainless steel body and IP67 protection level make it ideal for installation in challenging environments such as construction machinery, factory floors, and mobile hydraulic systems. The combination of a G1/4 male threaded pressure port and a sealed M12 electrical connector ensures a secure, reliable interface for both fluid and electrical connections.

Key Features

Micro-Fused Silicon Strain Gauge: Provides high sensitivity and excellent repeatability for precise pressure measurement.
Leak-Free Monolithic Design: Elastomer constructed without O-rings or welds for superior reliability and corrosion resistance.
Integrated Wide-Range Temperature Compensation: Digital compensation from -10°C to +70°C minimizes zero and full-scale thermal drift to <0.02%FS/°C.
Industrial-Grade Housing: Constructed from corrosion-resistant stainless steel with an IP67 environmental seal.
High Overload & Vibration Resistance: Engineered to withstand the dynamic conditions of hydraulic and mobile equipment.
Excellent Long-Term Stability: Drift is guaranteed ≤±0.2% of full scale per year.
Broad Media Temperature Range: Can interface with media from -40°C to +125°C.
Simple Two-Wire 4-20mA Interface: Enables easy wiring and integration over long distances with high noise immunity.

Applications

Mobile Hydraulic Systems: Real-time pressure monitoring in excavator booms, crane hydraulic circuits, and dump truck lifting cylinders.
Industrial Process Control: Precise pressure regulation and monitoring in compressor stations, gas dispensing systems, and pneumatic control panels.
Machinery Manufacturing & Testing: Integration into automated test stands for hydraulic component validation and production line quality control.
Fluid Power Systems: Monitoring pump outlet pressure, filter differential pressure, and accumulator pre-charge in industrial water treatment and pumping stations.
Refrigeration & HVAC: Safeguarding and controlling pressure levels in refrigeration systems and chiller units.

Frequently Asked Questions

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

The FST800-4001 uses a standard 2-wire current loop. You connect the positive supply voltage (9-30V DC) to the positive terminal via the M12 connector, and the 4-20mA signal is drawn from the same positive line through the sensor. The return wire completes the loop to your PLC or data logger's analog input, which typically includes a precision resistor to convert the current to a voltage.

Is this sensor suitable for use with aggressive hydraulic fluids or gases?

Yes. The sensor's wetted parts, including the pressure port and diaphragm, are constructed from corrosion-resistant stainless steel. The monolithic, weld-free elastomer design provides excellent resistance to a wide range of media, including standard hydraulic oils and many industrial gases. Always verify chemical compatibility for specific aggressive media.

What is the difference between operating temperature and media temperature?

The operating temperature range (-10°C to +70°C) refers to the ambient environment where the sensor's electronics are calibrated and perform within specification. The media temperature range (-40°C to +125°C) refers to the temperature of the fluid or gas being measured at the pressure port. The sensor can withstand this wider media range, but accuracy is guaranteed within the compensated operating temperature limits.

Can this sensor be used to measure vacuum or absolute pressure?

No. The FST800-4001 is specifically a gauge pressure sensor, meaning it measures pressure relative to the local atmospheric pressure. It is calibrated with the vented side of the sensing diaphragm referenced to ambient air. It cannot measure absolute pressure (referenced to a perfect vacuum) or differential pressure between two separate fluid lines.

Does the IP67 rating allow for permanent submersion?

No. An IP67 rating indicates the sensor is protected against dust ingress and can withstand temporary immersion in water up to 1 meter for 30 minutes. It is not designed for continuous, long-term submersion or high-pressure water jets. For permanently submerged applications, a sensor with a higher IP rating (like IP68 or IP69K) and appropriate sealing materials would be required.
