Calex PC21LT-0 传感器
Infrared Sensor, Current, IP65
Calex
High Performance PyroCouple Series High quality, low cost, non-contact Infra-red temperature sensors suitable for measuring the temperature of inaccessible or moving objects and materials. Fast response with high stabilityTypes available with air/water cooled housingsQuick and easy to installAvailable as either two-wire or four-wire unitsTwo-wire 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 sensors transmit the target temperature as a 0-50 mV or thermocouple output, and in addition transmit the internal 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. Measurement temperature range 0 to 250°C Ambient operating temperature range 0 to 70°C Accuracy ±1% rdg. or ±1°C, whichever is greater Response time 240 ms to 90% Emissivity (fixed) 0.95 Housing material Stainless steel Mounting thread M16 x 1mm Electrical connections Pre-wired, 1m cable Supply voltage 24Vdc nom., 28Vdc max.
