Material
St. St. 316
Accessory thread M36 x 1.5 mm
Sensor to junction box ¾” NPT or M25 x 1.5 mm
*) Extended range: The sensor extended temperature range is greater than the maximum specified in
EN 60079-29-1. It is therefore strongly recommended that if used above +55 °C or below -25 °C the
sensor is calibrated at the operating temperature.
**) The storage temperature range is also valid for spare parts and accessories
