The Strap-On temperature sensor is asingle point temperature sensor that is designedfor use with electronic controllers in commercialheating and cooling building managementsystems. It is available with multiple thermistorand RTD options.The Strap-On series sensor can be used to monitorpipe sizes from 1-1/4” to 10” (31.75mm to 254mm).The “-S” Model is designed to fit around an 1-1/4” to 4”(31.75mm to 101.5mm) pipe. The “-S10” Model isdesigned to fit around a 2” to 10” (50.8mm to101.5mm) pipe. The “-S” Model can be mounted tolarger diameter pipe by adding an additional hoseclamp.For optimal temperature measurement, followthese tips:• Clean the pipe with an emery cloth or filebefore applying thermal grease and insulatethe sensor from the effects of ambient air.• The sensing element is the 1.5” square copperplate. Applying thermal grease in-betweenthe sensor plate and pipe is recommended,but not required.MOUNTING INSTRUCTIONSIf there is insulation around the pipe, remove asection of insulation to accommodate the widthof the junction box and sensor. The sensorshould be mounted on the top or side of thepipe. Press the sensor copper plate to thecleaned pipe surface, and tighten the clamparound the pipe. Take care not to overtightenclamp to prevent damage to the copper heattransfer plate or sensor.PLASTIC BOX (-PB)3.60"(91.44 mm)2.25"(57.15 mm)GALVANIZED ENCLOSURE (-GD)2.31"(58.67 mm)4.18"(106.17 mm)NEMA -4X (-4X)2.55”(64.77 mm)FOAM PAD, WILL COMPRESSUPON INSTALLATIONADJUSTABLEFOAM PAD, WILL COMPRESSUPON INSTALLATIONADJUSTABLE3.70"(93.98 mm)FOAM PAD, WILL COMPRESSUPON INSTALLATIONADJUSTABLE
