Original tags also reference ATEX, Ex d IIC, flameproof and “0-100”. The temperature unit/range basis, actual hazardous-area markings and applicable certification have not been established here.
Confirm the installed head/bracket configuration, sensor-input compatibility and current calibration records before ordering. C4 and Q4 are recorded option descriptions, not proof that either calibration certificate is supplied or current. No separate sensor element, temperature switch or complete controller is specified as included. Hazardous-area suitability must be checked against the actual unit and installation requirements.
