If you need an LSM-11 now, this is the part to choose

Assembled in the UK LSM-11 replacement direct-fit uses our proprietary polishing process to give an LSM-11 compatible output. We've improved our processes and now this sensor gives performance virtually indistinguishable from a real LSM-11. You will require an EMU-BOILER-EXTN-1500 extension cable (reusable) to connect to the boiler's screw terminals.

Features:

1. Uses sensor of traditional construction, polished using our own processes to give an LSM-11 compatible output. Uses thimble type construction, exactly like an LSM-11
2. Multiplug gives ease of replacement, extension cable to connect to boiler screw terminals is only needed once
3. Traditional two-part LSM-11 connectors are available on request
4. Plug and play - needs no calibration or set-up
5. Sensing element made in USA
6. All sensors are bench tested by a technician and calibrated for specific use for this purpose
7. Please leave multiplug attached, it's an integral part of our calibration system

Please refer to this product as LSM11B, or 0258104000. This will replace all the 025810400x series sensors. These sensors are available immediately and will continue to be available alongside the EMU control box. Extension cable is now included with the sensor for no charge.

Amongst others, fits these boilers using LSM11 four wire sensors:

• Froling
• Vigas gasification boilers
• Kriger industrial boilers
• Woodtek

Custom designed and manufactured in the UK. LSM-11 replacement module allows modern sensors to be used. Sensors sold separately.

This unit provides an exact modelling of the traditional LSM-11 output curve for excess oxygen (lean) outputs as found in biomass combustion processes. Also provides best-fit LSM-11 emulation at rich/lean crossover and in the rich output regime. Compatible with at least three families of narrowband sensor, so reducing to almost zero chances of obsolescence. Available soon.

Features:

1. Uses sensor element of modern construction, retaining the robustness, long life and simplicity of a narrowband sensor
2. Precision circuitry models LSM-11 output precisely for the excess oxygen regime (lean) as found in biomass combustion processes.
3. Plug and forget - needs no dismantling, no assembly, no calibration or set-up procedure at all, even when swapping sensors between types
4. Rich and lean regimes both supported even on the basic unit. Output response can be shaped to customer requirements if needed
5. Industrial grade components rated to 110 degrees C ambient temperature, through-hole PCB construction with sealed box to IP54 gives vibration resistance and long life
6. Multiplugged unit connects directly into where the old LSM-11 fits. No adjustments required. Sensor is multiplugged for decreased downtime. Swap a sensor in under a minute!
7. 12v AC in standard form, or 12v DC / other voltages on request. Tolerant from 10 volts to around 15 volts in standard form.
8. Analogue output protection, diode clamped to + / - 5 volts, normal output range is -0.5volts to +1 volt
9. Optional digital serial output can be used to provide O2 percentage concentration information to control any industrial combustion process. Analogue LSM-11 compatible output is standard
10. All sensors are bench tested by a technician and pre-calibrated for specific use with this module.

Please contact us if you need further information. Please note, this unit is still in development.

Assembled in the UK oxygen sensor for LSM-EMU control unit. The most accurate narrowband sensor we sell. Sensors replaced separately, supplied with multi-plug for EMU control unit. High accuracy and individually calibrated, modern construction for long life.

Extension cable from screw terminals to 4-way multiplug, required for LSM11B sensor and also for LSM-EMU sensor interface. Heat resistant woven glass silicone sleeving, connector rated to IP54. Fit once, use many times. Made in the UK.

Lambda Sensor power supply unit for heater element. Made in the UK.

Feature List:

• Intended for powering lambda sensor heater element
• 1500mm cables
• 100-240VAC input
• 12v DC output multiplugged for convenience
• 3.8A current output
• Short-circuit and overcurrent protected, also features additional backup ceramic fuse
• Fire retardent housing
• Vented casing, convection cooled
• Suitable for all our 4-wire oxygen sensors
• Also suitable to power main PCB if it has a separate 5v regulator on-board
• Replaces poorly performing original PSU such as halogen downlighter PSU's (entirely unsuited for lambda use)

Six way connector and cable improved over the original by using colour coded wires rather than all-black. Made in the UK.

Feature List:

• Intended for replacement Ekogren lambda harness and other uses
• 1500mm cables
• Replaces the following part numbers:
• Deytrade 1928404900-PT

Wiring codes as follows:

Pin Posn	Wire Colour
1	RED
2	YELLOW
3	WHITE
4	GREY
5	GREEN
6	BLACK

Example connection of our 6-wire lambda sensor extension cable harness to Ekogren boiler control unit

• Fits Froling P4 wood pellet boiler
• Fits EkoGren 60kW Pellet burner
• Fits boilers using part number 69001 BreitbandSonde
• Suitable replacement for 0258017025 and 0281004137.
• Uniconfort boiler (with remote lambda interface box)

Please re-use the collar adaptor from the old sensor if it has one. This sensor will solve problems associated with sensor output drift - a natural effect of sensor ageing but also caused by contaminants (problem exacerbated by using unclean fuels, eg. painted wood panels etc.) thus making the boiler control system stick in ignition mode and display an error code refusing to enter heating mode.

Lambdapower branded. German sensor element. Assembled in the United Kingdom. Packed in anti-static protective bag.

Genuine Bosch, retail boxed in original packaging. Generally you can use our own 69001 listed above, but we also offer this if you are bound by type-approval, or specifically need the LSU4-93 sensor.
