Lambdapower sell a variety of sensors suitable for wood burning stoves, oil fired boilers, biomass boilers, industrial furnaces, drying ovens, steel annealing plants, and other process control tasks and industrial-only uses. We have our own-brand replacement for LSU4-9 sensors, and a new improved LSM11B replacement for legacy applications using 4-wire sensors.

A selection of LP sensors from the first LSM11B batch ever made


Our own LC69001 sensor is a direct upgrade for the Bosch LSU4-9 sensor used in various applications:

  • Froling P4, various
  • Gilles HPK-RA 30
  • Herz wood burning stoves
  • Stoker wood burning stoves
  • Mawera
  • Slurry / bio Drying furnaces
  • Hoval

Manufactured in the UK, we present the improved version of Lambapower's LSM11 replacement. This sensor is updated from Phase I to Phase II. Features improved sensor performance, and rewritten datasheet (version 2.x) with revised technical content, in response to customer feedback.

  • Lambdapower Branded and Serial Numbered for ISO9001 compliance
  • Manufactured in the UK
  • Each item is individually tested - this ensures consistently high quality
  • "Gold" graded sensors are available for laboratory uses (better than 15ppm accuracy)
  • Naturally smooth progressive output - no annoying ADC quantisation steps or heater element MOSFET PWM switching noise typically found with digitally processed wideband sensors
  • As quick as 200mS response time (Test conditions: ambient 15 minutes warmup time, then reference gas -3% O2 concentration)
  • Lifespan up to 8 times better than spurious or generic sensors
  • Correct heater rating is recognised immediately as LSM11 by the controller
  • Industrial users qualify for discount on multiple items - please contact us for a quotation

New Product Updates from Phase I to Phase II:

  1. Improved LSM11 compatibility for industrial boiler applications
  2. More stable output in free air and during use
  3. Improved hysteresis characteristics (better return-to-zero performance)
  4. Two-part "Power Timer" connector is now a standard part
  5. Thicker cables to reduce voltage losses
  6. Larger vents to improve resistance to fly ash
  7. Improved manufacturing procedures and tightened tolerances

Please note these parts are generally manufactured specially for each order. Some parts are usually available ex-stock for small orders.

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

  • Froling
  • Vigas
  • Kriger (requires Instatherm® Interface)
  • Woodtek (requires Instatherm® Interface)
  • Hoval (requires Instatherm® Interface)

The LSM11B is NOT suitable for 4-wire NGK OZA685-WW1 (HS Kabeltechnik 118.02-7100). ** Replacement for this part is in development **

The LSM11B is for professional use only, it is not suitable for DIY fitment.

LSM11B typical output graphs

Example remote telemetry, 0.9MW pellet burner fitted with LSM11B sensor, Flue Oxygen Content vs Time. Boiler self-cleaning cycle every couple of hours.


A selection of randomly chosen sensors showing comparison between original LSM11 and new improved LSM11B. Adjusting the static set-point will move the graphs along the Y-axis. Shows mV output vs Oxygen content using a fan stirred heated mixture of plain air and inert reference gas in varying proportions.


Example (worst-case) deviation of LSM11B from original LSM11 output under identical conditions. This is NOT a measure of absolute accuracy, it is a measure of difference of outputs. Both the LSM11 and LSM11B will have their own deviations from the ideal curve depending on the particular sensor under test. This can be dialled out using static offset adjustment.


Example output from our own design LSM11B linearising interface to demonstrate that we can achieve five wire wideband comparable performance using a four wire sensor.
