Kjaerulf Pedersen a/s designs and manufactures temperature sensors, thermocouples, thermowells and condition monitoring sensors for the power and energy sector — built to DIN and IEC standards and configured to the individual measuring point, from the steam circuit to 1700 °C in the combustion zone.

Application focus

Waste incineration & waste-to-energy

Corrosive flue gas and constant high temperatures wear ordinary sensors down. KP builds incineration thermocouples to match the zone they measure in: type K and N for combustion zones, noble-metal type S, R and B where temperatures and stability demands are highest — ceramic-protected up to 1700 °C.

The program

The measuring points of an energy plant

Choose by what you need to measure — every sensor is configured to order in length, material, connection and output.

AC/ACC high-temperature thermocouple with ceramic protection tube
High-temperature thermocouples

Furnace, kiln and flue gas measurement up to 1700 °C. Metal sheath or gas-proof ceramic inner tube; thermocouple types K, J, E, N, R, S and B.

TM2 bendable mineral-insulated thermocouple sensor
Mineral-insulated sensors

Bendable MI thermocouples up to 1800 °C (depending on type) and MI RTDs up to 600 °C — fast response, vibration-proof, fits confined installations.

Temperature Sensor Type B with interchangeable measuring insert
Steam, water & process

Two proven systems for boiler and turbine circuits: Type B with interchangeable measuring insert, and the DIN 43772 weld-in programme — D/DS/DDS sensors in MA-PW D thermowells, up to 500 bar and 650 °C depending on material.

RTBC bearing temperature sensor
Bearings & surfaces

Bearing sensors — including extended probes for deep measuring points — and surface-mounted sensors for turbines, gen sets and rotating equipment.

All sensors are available with head-mounted transmitters — 4–20 mA, HART, Profibus and EEX variants — for direct integration with plant control systems.

Beyond temperature

Catch developing faults before they become a forced outage

Pumps, fans, turbines and generators wear over time, and a change in vibration is the earliest sign — a developing fault shows in the vibration signature at roughly 10% progression, long before a temperature alarm (around 40%) or an audible symptom (around 60%). KP's condition-monitoring sensors watch for that change continuously, so you plan and target maintenance before a forced outage.

KPV200 — vibration

Continuously monitors vibration on motors, pumps, fans, turbines and other rotating equipment. A change in the vibration signature is the earliest indicator of bearing or component wear — giving you the lead time to act before a breakdown and focus maintenance where it's needed.

KPM100 — motion

Angle, direction and acceleration — tower sway and foundation movement on wind assets and structures, with early warning when something moves in ways it shouldn't.

KPH300 — humidity & dewpoint

Humidity, temperature and dewpoint in one IP67 sensor — reduces condensation risk in enclosures, substations and technical rooms.

Why KP

Why energy professionals choose KP

Standard where it matters

DIN 43772 thermowells, IEC 60584-1 thermocouples and IEC 60751 RTDs — and thermowell systems with interchangeable inserts. Our sensors replace what is in your plant 1:1, without redesign or requalification.

Material knowledge

The right material for the medium: DIN boiler steels 13CrMo44 and C22.8 for high-pressure steam, acid-proof 316Ti and 316L, heat-proof steel and gas-proof ceramics for the hottest zones — special materials on request.

Configured to your measuring point

Standard designs, your dimensions: immersion length, process connection, cable, plug and output are built to order — also in small volumes.

In-house development & production

Every sensor is developed and manufactured by KP — you talk directly to the people who design and build it, not to a reseller.

Good to know

Frequently asked questions

Which temperature sensors are used in power plants?

Pt100 RTD sensors are typically used in steam and water circuits, on bearings and in auxiliary systems, while thermocouples handle combustion chambers, flue gas and other high-temperature zones. Thermowells protect the sensors and allow replacement without opening the process.

When should I use a thermocouple instead of an RTD?

As a rule of thumb: RTDs (Pt100/Pt1000) offer the best accuracy up to around 600 °C; above that, thermocouples take over. Type K and N cover most combustion applications, while noble-metal types S, R and B are used for the highest temperatures and where long-term stability is critical.

Can a sensor be replaced without shutting down the plant?

Yes — with a thermowell or a modular sensor with a replaceable measuring insert (such as Type B, or D/DS/DDS sensors in DIN 43772 weld-in thermowells), the sensing element can be exchanged without emptying or interrupting the process.

Which sheath and thermowell materials do you offer?

Materials are matched to the medium and the plant specification: DIN boiler steels 13CrMo44 and C22.8 for high-pressure steam and weld-in thermowells (DIN 43772), acid-proof AISI 316Ti and 316L for general and corrosive service, and heat-proof steel and gas-proof KER ceramics for the hottest zones. Special materials on request.

Do your sensors integrate with our control system?

Yes. Sensors are available with head-mounted transmitters with 4–20 mA, HART or Profibus output, and the KPV200 vibration sensor connects directly to a PLC via MODBUS — plug and play.

Do you also cover wind, solar, biogas and fuel cells?

Yes. Operating assets are covered here under Power & Energy. If you are building the technology itself — wind turbines, solar plants, hydrogen and Power-to-X, biogas plants or fuel cells — see our Green Tec industry area.

Can KP build a sensor that matches our existing installation?

Yes — that is our core business. We manufacture to your specification: immersion length, sheath material, process connection, cable and plug, sensor element and output. Send us the data of the existing sensor and we will match it.
