INE7-T

Detector in explosionproof enclosure

Explosion-proof enclosure detector, similar to the INE7 series detectors, equipped with an LCD touchscreen display. Thanks to this feature, calibration, verification, and maintenance operations can be performed without opening the enclosure.

This characteristic allows safe operation even in classified environments. 

The detectors from the INDUSTRIAL series are manufactured using the most modern reflow and SMT construction techniques. They use the latest generation of microprocessor technology to deliver fast response and ensure accuracy and reliability.

The sensitive element is connected to an interchangeable device component which allows installers to replace the sensor cap (the part susceptible to wear and tear) without needing to recalibrate the device.

The complete product line includes a wide array gas leak detectors, all available in explosionproof or dustproof enclosures to satisfy even the most exacting requirements.

During the installation phase or maintenance sessions, you can interface INDUSTRIAL series detectors with a PC (via an INA55-700 interface) or Android Smartphone (via an INA55-701 interface) in order to configure the parameters, change the intervention thresholds, check the gas-level readings and/or simulate alarm, pre-alarm and fault conditions.

  • Selectable delays from 0 to 240 seconds for each individual threshold.
  • Reading compensation system in accordance with ambient temperature.
  • Replacement of sensor cap directly on-site without need of titrated gas canisters.
  • Connection to PC (via INA55-700 interface) or Android SmartPhone (via INA55-700 interface) for threshold, filter and delay settings, real-time Value Readings and simulation of alarm, pre-alarm and fault conditions.

Orders for Detectors must specify not only the type of enclosure, but also the type of gas, the technology of the sensitive element and the type of output interface. Following is a schematic representation of the order codes.
