Fits fixed non-contact temperature where you need a Thermalert/Compact GP two-piece system: 1/8 DIN monitor plus GPR/GPS sensing head for −18 to 538 °C.
Key advantages
- System — Two-piece fixed IR: 1/8 DIN monitor + GPR/GPS sensing head
- Range — −18 to 538 °C (0 to 1000 °F); 8 to 14 µm spectral response
- Accuracy — ±1% of measured value or ±1 °C (2 °F), whichever greater (mA output)
- Optics — Standard/close-focus GPR; GPS laser-sighted head with 50:1 D:S
- Outputs — User-defined 4–20 mA or thermocouple (J/K/E/N/R/S/T); dual alarm setpoints
Typical applications
- Continuous process surface temperature on plastics, paper, or food lines.
- OEM machine monitoring where a compact fixed head and panel monitor fit the enclosure.
- Sites needing 4–20 mA or thermocouple retransmission into PLC/DCS.
Selection guide
- Head — GPR standard/close-focus vs GPS laser-sighted 50:1
- Output — 4–20 mA vs thermocouple type; dual alarm setpoints
- Emissivity — Digitally adjustable 0.1 to 1.09 for the target surface
- Power — Universal 110–220 VAC monitor supply
Common mistakes
- Using 8–14 µm on shiny metals without emissivity correction or a different spectral head.
- Mounting the head beyond the optical distance for the selected D:S.
- Ordering thermocouple output when the PLC only accepts 4–20 mA.
When to RFQ / what to tell us
- Target material, temperature span, and mounting distance.
- GPR vs GPS head; output type; alarm needs.
- Quantity and ship-to.
