دستگاه مانیتورینگ دو کاناله گاز برند MSA مدل ۵۸۰A
(MSA Brand Dual Channel combustible monitor Model 580A)
Description
The Model 580A Controller is a two-channel system designed to continuously monitor for potential explosive concentrations of most combustible gases/vapors.
The 580A consists of a controller plus two sensor assemblies.
The sensors are monitored independently.
The controller can be wall, panel or rack mounted in a non-hazardous area.
The system operates in the range of 0-100% LEL (Lower Explosive Limit) and is calibrated to a particular gas or vapor.
User interfaces are provided so that the operator may interpret and direct the Model 580A in the performance of its various functions.
User interfaces consist of a digital display, status indicators, a channel/select button, a mode button, and a reset button.
The system operates on 117 VAC, 50-60 Hz (optional 220 VAC, 50-60 Hz), or 24 VDC primary input power with the capability of 24 VDC battery backup.
Nominal power consumption is 18 watts.

Sensor Elements
General Monitors’ sensors are designed for reliable performance and long life.
Each sensor must undergo extensive burn-in and rigid quality control procedures before shipment.
The sensors consist of two catalytic bead elements in a balanced Wheatstone bridge circuit.
These low temperature catalytic beadsensing elements require minimal sensor excitation current, greatly increasing sensor life.
