Non-contact infrared temperature sensors

The PyroCouple series is a range of high-quality, low-cost, compact sensors which measure the temperature of inaccessible or moving objects and materials. They can measure temperatures from -20 to 500 °C, accurately and consistently, with a response time of 240 ms.

Two-wire PyroCouple sensors transmit the target temperature as a 4-20 mA output and offer a simple solution for most non-contact temperature measurement applications.

Four-wire PyroCouple sensors transmit the target temperature as a 0-50 mV or thermocouple output (type J, K or T) plus the internal sensor temperature as a 4-20 mA output. This second output can be used to ensure that the sensor is being operated within the correct ambient temperature limits and prevent damage caused by overheating or overcooling.

All PyroCouple sensors are fitted with precision Germanium lenses for accurate optics. Model PC21 has 2:1 optics making it suitable for most applications where the sensor can be mounted close to the target. Model PC151 is designed for small or distant targets and has an optical resolution of 15:1. Model PC301 is designed for very small or distant targets and has an optical resolution of 30:1.

The sensor is 103 mm long by 18 mm diameter and made of polished stainless steel, sealed to IP65, making it suitable for food and pharmaceutical applications.
