NEW PyroCouple Compact Non-Contact Temperature Sensor with optional Dual Output Temperature range: -20C to 500C Emissivity setting: fixed at 0.95 Two-wire 4-20 mA output or four-wire voltage/thermocouple output Four-wire unit also provides inter nal sensor temperature Field of view: 2:1, 15:1 or 30:1 Fast response with high stability Stainless steel housing, sealed to IP65 Quick and easy installation Optional air/water cooled housing, air purge collar, laser sighting tool shown actual size and mounting brackets The PyroCouple Series is a range of high quality, low cost, compact sensors which measure the temperature of Two-wire units (option 0) Display/Controller inaccessible or moving objects and Power Supply PWR+ +- materials. They measure temperatures - from -20C to 500C, accurately and PWR- + consistently, with an outstanding 4-20mA response time of 240 ms. 4-20mA = Target Temperature PyroCouple sensors are available as either two-wire or four-wire units. Two-wire PyroCouple sensors transmit the target temperature as a 4-20 mA Four-wire units (options 1 to 4) Display/Controller output and offer a simple solution Power Supply PWR+ +- for most non-contact temperature - measurement applications. PWR- + 4-20mA Four-wire PyroCouple sensors transmit 4-20mA = Sensor Temperature the target temperature as a 0-50 mV or thermocouple output (type J, K or T) Display/Controller plus the internal sensor temperature as OP- - a 4-20 mA output. This second output can be used to ensure that the sensor OP+ + is being operated within the correct mV/TC = Target ambient temperature limits and prevent Temperature damage caused by overheating or overcooling. It can also be used to give an approximate indication of the air temperature surrounding the sensor.All PyroCouple sensors are fitted with precision germanium lenses for DIAmETEr OF TArgET SPOT mEASUrED VErSUS DISTAnCE FrOm accurate optics. model PC21 has SEnSIng hEAD 2:1 optics making it suitable for most applications where the sensor can be Distance: Sensor to object (inches) Distance: Sensor to object (inches) Distance: Sensor to object (inches) 0 4 8 0 19.7 39.4 0 19.7 39.4 mounted close to the target.
