Frequently Asked Questions About This Product

A two piece fiber optic pyrometer has a stainless steel optical probe joined by fiber to a separate signal processor with display. The IRFP probe sits near the hot target while the display stays in a cooler area, reading 385°C to 1600°C.

The probe can sit near a hot target while the signal processor and display stay in a cooler area, which protects the electronics in high-temperature locations.

1MS covers 680°C–1600°C and 2MH covers 385°C–1600°C, depending on the selected variant.

The IRFP Series offers 120:1 optical resolution, which supports small or distant hot target measurement.

The IRFP provides a four-wire 4 mA–20 mA analog output and RS485 Modbus RTU digital communication for continuous monitoring.

Fiber optic cable lengths are 3 m standard, with 5 m, 10 m and 15 m optional, rated from -20°C to +250°C.

Users should check target temperature, spot size at distance, fiber cable length, mounting and output requirement.
