They measure temperatures from -20C to 500C, accurately and consistently, with an outstanding response time of 240 ms. PyroCouple sensors are available as either two-wire or four-wire units. Four-wire units (options 1 to 4) PWR+ Power Supply + - PWR- 4-20mA Display/Controller + 4-20mA = Sensor Temperature Display/Controller OP- - OP+ + mV/TC = Target Temperature 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. It can also be used to give an approximate indication of the air temperature surrounding the sensor.

Min. Sensor Voltage 6 V DC Max. Loop Impedance 900 ( 4-20 mA output) Output Impedance 56 (voltage/thermocouple output) 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. These compact sensors are small enough to fit almost anywhere and their rugged stainless steel housings make them ideal for applications where cleanliness and hygiene are paramount. Accessories Fixed mounting bracket The L-shaped fixed mounting bracket offers a rigid support for the sensor and allows fine adjustment in a single plane. Adjustable mounting bracket The adjustable mounting bracket consists of a fixed mounting bracket plus another L-shaped bracket. When assembled as shown the adjustable mounting bracket offers a rigid support for the sensor and allows fine adjustment in two planes. Air purge collar The air purge collar is used to keep dust, fumes, moisture and other contaminants away from the lens. Air flows into the fitting on the side and out of the aperture at the front. Mechanical Construction Stainless Steel Dimensions 18 mm diameter x 103 mm long Thread Mounting M16 x 1 mm pitch Cable Length 1m Weight with Cable 95 g ENVIRONMENTAL Environmental Rating IP65 Ambient Temperature Range 0C to 70C Relative Humidity 95% max. non-condensing Air/water cooled housing The air/water cooled housing allows the sensor to withstand ambient temperatures which exceed the normal 70C limit. Air or water (depending on the degree of cooling required) flows into one of the fittings on the side and out of the other. To prevent condensation forming on the lens, the air/water cooled housing is supplied complete with an air purge collar. Please note, the air/water cooled housing must be ordered with the sensor and cannot be fitted by the user.
