UVS 10D0G1 uv-detector KROM SCHRODER sensor uv

uv sensor uvs 10D0G1 KROM SCHRODER

• Virtually immune to interference due to its insensitivity to daylight,
infrared radiation and incandescent bulbs
• Maximum safety thanks to protection against discontinuity or
short-circuit on the flame signal cable
• Suits industrial needs due to robust design
• Complies with the requirements of EN 298 in conjunction with
Kromschröder automatic burner control units and burner control
units

1 Application
For monitoring gas burners of unlimited capacity with
or without fan, on hot-air furnaces, gas-fired boilers, industrial furnaces and excess-gas flaring installations in
conjunction with Kromschröder automatic burner control units and burner control units.
The UV sensors monitor the gas burners in intermittent
operation.
The burners can either be ignited directly or operated as
pilot and main burners.

UVS 10
UV sensors UVS 1, UVS 6 and UVS 8 can be replaced
by using various adapters with a heat guard made of
quartz glass.

3 Function
The UV tube detects the ultraviolet light of a flame. In
the case of incident UV light, alternating current flows
through the UV tube and is converted into a DC signal
by the UV sensor. The DC signal can be processed by a
flame signal amplifier.
The UV tube does not respond to daylight, incandescent bulb light or infrared radiation emitted by hot
workpieces or red-hot furnace walls.
The designed lifetime of the UV tube is approximately
10,000 operating hours. For safety reasons, it must be
replaced after this period.
UVS 10

A quartz glass heat guard insulates the UV tube against
the hot furnace atmosphere and protects against moisture, dirt and heat.
