Description

The FST600-400A infrared temperature sensor operates on the principle of detecting infrared radiation emitted by a target object. Its internal optical system focuses energy onto a photodetector, generating an electrical signal proportional to the target’s temperature, which is then conditioned into a stable 4-20mA output. This non-contact method ensures the measurement does not influence the temperature of the object being sensed, providing accurate and reliable data.

Engineered for industrial durability, the sensor is housed in an IP65-rated enclosure, protecting it from dust ingress and water jets. It is designed for continuous operation in ambient temperatures from 0 to 60°C, making it suitable for integration into factory automation, process control panels, and energy management systems where reliable, isolated temperature monitoring is critical.

Key Features

  • Non-contact infrared thermometry for safe, non-invasive temperature measurement
  • Industrial-standard 4-20mA analog output ensures noise-immune signal transmission over long distances
  • IP65-rated housing provides robust protection against dust and water spray
  • Fast 300ms response time enables monitoring of rapidly changing thermal processes
  • Wide 9-30VDC operating voltage simplifies integration with common industrial power supplies
  • 20:1 optical resolution (distance-to-spot ratio) for targeted measurement of small or distant objects
  • ±2% accuracy for reliable process control and monitoring applications
  • Integral 1.5-meter output cable for direct connection to control systems

Applications

Frequently Asked Questions

What is the output signal of the FST600-400A sensor and how do I interface with it?

The sensor provides a standard 2-wire 4-20mA analog current loop output. Connect the integral 1.5-meter cable's two wires to a compatible PLC analog input module, data logger, or 4-20mA receiver. The loop is powered by the 9-30VDC supply connected in series, making wiring straightforward for industrial control systems.

What does the 20:1 optical resolution specification mean for mounting this sensor?

A 20:1 distance-to-spot (D:S) ratio means that at a distance of 20 units (e.g., 200mm), the sensor measures the average temperature within a spot diameter of 1 unit (e.g., 10mm). For accurate measurement, you must mount the sensor so the target object completely fills or exceeds this measurement spot size at the chosen installation distance.

Can this sensor be used outdoors or in wet environments?

With its IP65 rating, the sensor is protected against dust ingress and low-pressure water jets from any direction. This makes it suitable for use in damp industrial environments or under covered outdoor installations. However, it is not submersible and should not be exposed to direct, high-pressure water streams or fully submerged.

What is the required power supply and how is it connected?

The sensor operates on a wide-range 9-30VDC power supply. It uses a 2-wire loop-powered configuration: the positive supply terminal connects to the positive wire of the sensor's cable, and the negative wire connects to the positive input of your 4-20mA reading device (like a PLC analog input), which is then connected back to the power supply negative, completing the loop.
