Calex Infrared Temperature Sensor Threaded Mount 18mm Diameter 0 °C to 500 °C 28V PMO-151-HT-C

Calex PMO-151-HT-C is a high-precision Infrared Temperature Sensor designed for industrial, laboratory, and automation applications requiring reliable temperature monitoring within 0 °C to 500 °C.

The sensor features a threaded mount type and a diameter of 18 mm, combining robust aluminium and 316 stainless steel materials to withstand challenging operational conditions. The sensing head has an IP65 rating, ensuring protection against dust and water ingress, enabling deployment in harsh environments.

The device uses fixed emissivity at 0.95 and operates over a spectral range of 8 to 14 μm with an accuracy of ±1% or ±1ºC, whichever is greater. Its quick response time of 240 ms and 2-wire 4-20 mA loop-powered output facilitates seamless integration with automated control systems.

The sensing head is connected by a 3-meter cable, complemented by a 1-meter output cable with right-angled entry for space-sensitive installations. It withstands ambient temperatures up to 120 °C.

Certifications conform to IEC 61000-4-4, EN 55022A, EN 55022B, IEC 61000-4-2, IEC 61000-4-6, EN61326-1:2013, and IEC 61000-4-3 standards, ensuring electromagnetic compatibility and performance reliability.

Threaded mount type ensures secure and stable installation. Aluminium and 316 stainless steel housing for durability and corrosion resistance. Operating maximum ambient temperature up to 120°C for industrial environments.

High accuracy of ±1% or ±1ºC whichever is greater for precise control. IP65 rated sensing head for protection against dust and water ingress. Fixed emissivity setting at 0.95 for reliable infrared sensing. Spectral range from 8 to 14 μm suitable for most infrared temperature measurements.

Response time of 240 ms for rapid temperature detection. 2-wire, 4-20 mA output for loop-powered measurement interfaces. Right-angled cable entry designed for low-profile installation constraints.

This sensor is well-suited for applications in industrial process control, HVAC systems, agricultural machinery, manufacturing equipment, and laboratory temperature monitoring tasks.
