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.

Assembled in the UK LSM-11 replacement direct-fit uses our proprietary polishing process to give an LSM-11 compatible output. We have improved our processes and now this sensor gives performance virtually indistinguishable from a real LSM-11. Includes EMU-BOILER-EXTN-1500 extension cable (reusable) to connect to the boiler 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. Model LSM11-TC (Traditional Connector) available on request - this has the original Bosch two-part connector
  4. All sensors are bench tested by a technician
  5. Improved harness uses thicker cable to minimise voltage drop
Please refer to this product as LSM11B, or 0258104000. This is intended to replace all 025810400x series sensors. These sensors are currently in stock (December 2020) but we will not be manufacturing any more of these items during 2021. To replace LSM11B, a further supercession part (LSM11F) is in development.

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

  • Froling
  • Vigas
  • Kriger
  • Woodtek

Comparison Graphs (click to enlarge) 0.9MW Pellet Burner. Exact set point will depend on precise tolerances including boiler fuel type, age of original sensor, tolerance band of original sensor, but an average of between 7% - 9% gives best performance.

Analogue LSM11B linearisation interface, 0-10V linear output. Test range roughly 0.5% O2 to 19% O2. We could apply +0.5% correction to the boiler input PLC if improved response is desired within 1% - 3% range but remember LSU4-9 has inaccuracies of its own. All sensors drift with age. Output accuracy depends mostly on quality of interface design. With careful design the LSM11B can match a modern wideband sensor for accuracy.

LSM-EMU Control Unit Emulator: future-proof long term LSM-11 replacement

PRODUCT TYPEControl Unit
MANUFACTURERLAMBDAPOWER
PRODUCT NUMBERLSMEMU
OVERALL DIMENSIONS135x89x30 mm

A development of this module will shortly be replacing the LSM11B. We have listened to customer feedback as to features that are required. Custom designed and manufactured in the UK, this module allows modern sensors to be used in place of original Bosch LSM11 sensors (no longer available).

This unit provides an exact modelling of the traditional LSM-11 output curve for excess oxygen (lean) outputs as found in biomass combustion processes. In response to customer requests, features quick and convenient manual adjustment.

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. 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
  4. Control module requires just power (input) and signal connections (output). Takes its power from the original LSM11 heater supply
  5. Sensor is multiplugged for decreased downtime. Swap a sensor in under a minute!
  6. All sensors are bench tested by a technician and pre-calibrated for specific use with this module.
