Trolex develops gas detector for mines

World Coal,

Trolex has developed the SentrO P, an open protocol version of its proven Sentro gas detector, which allows direct integration with existing data networks. This means that when existing gas detectors fail, they can be quickly exchanged for the SentrO P and integrated into the system. Once replaced, they are able to communicate with other gas detectors and integrate into the data communications system.

US mining supply company Pillar Innovations recognised the benefits of replacing failed gas detectors with the new SentrO P. Adam Brenneman, director of marketing at Pillar, commented: “Pillar's customers trust us to source and supply ‘best of breed’ components throughout our systems, and that search led us to Trolex.

“The modular design of the Sentro line of sensors fits with the Pillar design ethos of using technological advancements to simplify processes. Trolex engineering staff have worked closely with Pillar counterparts to adapt an already great product to the US market. Extensive testing before deployment has a yielded a sensor which can be dropped into existing Pillar atmospheric monitoring systems. This will give our customers the flexibility to upgrade over time and keep costs in check.”

The new SentrO P contains a Sentro eModule, an intelligent standardised gas-sensing module, which stores dynamic data, its general condition and service history. The SentrO P can be easily integrated into proprietary information networks and can form part of a new data communications system using RS485 with Modbus protocol.

Entirely contained within a compact heavy-duty dual-wall shell, the gas detector features a large backlit LCD screen providing a concise menu driven calibration guide and sensor diagnostics.

The SentrO P is dust and moisture protected and the RS485 databus output permits up to 32 gas sensors to be networked on a single data cable for ease of installations and significant cost saving. In addition, an independent analogue output signal available on each sensor can be used to trigger a local audiovisual alarm if required.
