TT-O & TT-OR Outside Air Sensor

TT-O & TT-OR Outside Air Sensor

The TT-O-CVO temperature sensors are used to measure outside air temperatures. Units are available with a PT100 sensing element, which is located in a 10mm diameter cap in the lid for the TT-O-CVO and in a PTFE radiation shield for the TT-OR-CVO. The PTFE radiation shield will minimise the effects of direct sunlight and strong winds. The units use a 24vDC power supply to provide an active 0-10V or 4-20mA output option with pre-set temperature ranges (selectable via jumpers). A customised calibrated output range is also available. The housing is a grey PC/GF (Halogen free, flame retardant & UV stablised) enclosure with an IP65 Rating.
