Mantracourt's X24 range is an intrinsically safe version of its established T24 wireless telemetry sensor system, ATEX and IECEx approved for Zones 1 & 2 and developed after feedback from existing users of the T24 system.

Alongside its ATEX / IECEx status, modularity is the key feature. The X24 system comprises three products that are certified for use in hazardous areas - the X24-HD handheld display unit, X24-ACMI-SA cased transmitter and X24-SAe OEM transmitter. These products currently operate with strain bridge inputs and gather and transmit data from force, weight, torque and pressure sensors. Being fully compatible with Mantracourt’s T24 system, the data is transmitted to T24 receivers within the safe zone. This compatibility also means that the X24 system can be retrofitted, so companies can extend its existing T24 wireless network into hazardous areas, reducing installation costs and providing quick setup.
All three units display many of the notable features seen in equivalent products in the T24 system including high resolution/low noise electronics, long battery life of up to 5 years, proprietary license-free 2.4 GHz radio and a system range of up to 800m. However, new X24 products are manufactured with intrinsically safe electronics and are approved for use in explosive atmospheres Zone 1 and Zone 2, with the X24-SAe extending to dust Zones 21 and 22.
The transmitter module, X24-ACMi-SA measures strain bridge input and delivers it to the T24 receivers in the safe zone, or X24-HD in the hazardous area. It is housed in an environmentally sealed IP67 enclosure with battery holder for two Lithium Energiser L91 AA batteries. The X24-HD is a lightweight, portable design and certified to IP67. The product can display data from any transmitter detected or the operator can define up to 24 specific transmitters and each channel can be renamed. The X24-SAe is a product specifically for OEM sensor manufacturers. This transmitter, comprising a PCB board with antenna measures strain-bridge input and transmits data to X24 and T24 receivers. The PCB module provides OEMs and those who supply approved strain bridge sensor products with a quick route to manufacture.
