Room Temperature Alarms

ATEX Temperature Sensor for explosive atmospheres

Application of ATEX Temperature Sensor

We have designed the ATEX temperature sensor for rooms where a potentially explosive atmosphere can form. This occurs when a mixture of air gases, vapours, mists, or dusts combine in a manner that can ignite under specific conditions.

You have the flexibility to install the ATEX temperature sensor up to 100m away from the main Alarm panel. Its versatile application covers various industries, including fixed offshore platforms, petrochemical plants, mines, flour mills, and more.

Please note that Full compliance requires the installation of suppressors before the sensor cable enters the hazardous area.

How does the Temperature Sensor meet ATEX and IECEx ratings?

To comply with ATEX and IECEx standards, we mount the RTA2-2 temperature sensor inside a wall-mounted diecast aluminium enclosure that is ATEX and IECEx approved. Additionally, we equip the housing with an approved cable gland for cable entry and an external Earth bonding clamp. This ensures the enclosure can withstand an impact energy of 7Nm in accordance with IEC60079-0.

What can the ATEX Temperature sensor be connected too?

The ROOM OVER TEMPERATURE ALARM – TYPE RTA2-2. Designed to constantly monitor the temperature (-50°C to +50°C) in 1 or 2 zones.

The HIGH AND LOW ROOM TEMPERATURE ALARM – TYPE RTA-HL. System monitors the ambient room temperature and compares it to a high and low temperature alarm set point that can be adjusted internally between -50°C and +50°C.

What is ATEX?

The ATEX ‘Product’ Directive 94/9/EC came into force on 1st July 2003 before transitioning to the New Directive 2014/34/EU from 20th April 2016. The Directive ensures that equipment intended for use in environments where potentially explosive atmospheres can occur will not become a source of ignition. Specifically, the ATEX Directive ensures equipment is designed to meet the relevant Essential Requirements of the Directive(s).
