IR Flame Sensor Weishaupt QRB1B-B036A25A, 24131012022

The Weishaupt QRB1B-B036A25A IR flame sensor is a highly sensitive device for monitoring yellow flames in the visible range of the light spectrum during operation of a Weishaupt industrial liquid fuel burner. It is connected to the burner control using a 3-pin plug. Compact dimensions and a wide field of view make it easy to position and install the sensor.

Features and main parameters:

• Registration of infrared radiation of a liquid fuel flame;

• Sensitive element – ​​photoresistor;

• Direct and lateral measurements;

• The level of electrical protection of built-in components from dust/moisture is IP 40;

• High sensitivity, about 600 nm;

• Housing length – 65 mm;

• Three-pin plug to a 13-type plug-in terminal block;

• Compatibility with intermittent-cycle burner controls;

• Low maintenance requirements;

• Mounting on the burner in any orientation;

• Easy to install and connect;

• lock 418610960, 600566;

• replacement for the outdated model 24105012022.

More about the flame sensor

The flame sensor is equipped with a compact housing, inside which there is a sensitive element. The operating principle is based on the analysis of infrared radiation and the transmission of electrical signals about the control results to the furnace automatic control for fuel supply control.

A two-wire cable 360 ​​mm long with PVC insulation is rigidly connected to the housing. The plug connection simplifies the connection of the flame sensor to the burner automation.

Operating temperatures

The sensor is designed for operation at ambient temperatures of -20 ... + 60 ºC and relative humidity < 95%. Condensation, water ingress on the housing and icing should be excluded.

Protection against light interference

Flame sensors for Siemens QRB1 burners are capable of detecting radiation from other objects that fall into the visibility zone (lighting lamps, glare from facing bricks, sunlight, etc.). When choosing a location for installing the sensor, it is necessary to take standard measures to protect against light interference (detailed information is reflected in the sensor installation instructions).
