Pressure & temperature sensor
VADTel-SENS
Autonomous cellular pressure and temperature sensor for utility and industrial networks — ATEX version for Zone 1, IP65, up to 5 years on one battery.
-
Its own cellular link
Reports over GSM/GPRS or NB-IoT directly to the Data Platform — no separate telemetry module at the measuring point.
-
Zone 1 version
ATEX II 2G Ex d IIC T6 Gb X flameproof version for direct installation in Zone 1 hazardous areas.
-
Years on one battery
Battery options from 2,000 to 6,000 mAh are rated for 5,000 to 10,000 sessions — up to 5 years of autonomous operation, depending on the reporting interval.
VADTel-SENS closes the telemetry chain at the measuring point: it measures pressure and temperature every 5 to 600 seconds and sends the readings over its own cellular link to the Data Platform, with configurable alarm thresholds and event-driven reporting.
Applications include gas, water, heat, hydraulic, pneumatic, oil and fuel-related networks wherever the sensor configuration is compatible. Pressure trends also support indirect leak detection.
Full documentation — datasheet and EU product passport of the Ex version — is available on the IoT documentation portal.
