ACME GasPost - Model WS Series -Wireless Combustible Gas Sensor/Transmitter

Optionally the WS can also be powered from a 24VAC source. This version(WS-24) may have on-board relays to operate the ventilation equipment directly while transmitting their readings to the control panel for monitoring purpose only.

The WS employs a range of diffusion-type electrochemical and/or catalytic bead sensors capable of detecting a broad range of toxic and combustible gases. It provides a quick and reliable detection method of these gases with long term accuracy and trouble free operation.

Designed to act as fixed in-situ safety monitors, the WS transmitters automatically operate the mechanical ventilation system of a facility upon detection of hazardous gases, thereby protecting occupants, personnel and gas-sensitive goods and products. With the increased use of gas detection in maintenance and industrial facilities, the WS allows installers and users to meet code requirements economically using commercial-grade gas detection equipment.

The WS contains all the well-known standard features of ACME’s gas detection line; a robust enclosure, latest sensor technology and state-of-the-art electronics.
