Description
The Elco QRB1A-A050B70A flame sensor, art: 65326637 is used to register radiation emitted during the combustion of liquid fuel. It is integrated into intermittent-operation burners. It connects to the burner control unit to transmit signals about the presence/absence of flame. The power cable length is 710 mm.
Key features and characteristics:
- yellow flame control sensor;
- front and side visibility (90°);
- light-sensitive element – photoresistor;
- detector of normal sensitivity;
- protection against mechanical damage, dirt, external influences;
- dust and moisture protection according to IP 40 standard;
- two-core power cable with a length of 710 mm made of thermoplastic;
- without a soft plastic insert;
- flange mounting;
- temperature range (ambient): from -20 to +60 °C.
The sensor reacts not only to flame radiation, but also to other light sources (for example, light radiation from refractory brick in the combustion chamber).
Installation
The installation of the Elco QRB1A-A050B70A flame sensor is carried out on the flange. Thanks to the guide groove of the flange and the cam stop on the clamp, the device is securely fixed and accurately positioned, taking into account the best visibility of the flame.
