Industrial sensors for process & manufacturing — temperature, humidity, vibration and motion
Kjaerulf Pedersen develops and builds the sensors and measurement systems that watch your process — configurable temperature (RTD and thermocouple) from cold applications to high-temperature furnaces and kilns, plus humidity, dewpoint, vibration and motion — all built to your exact measuring point, from prototype to volume.
Kjaerulf Pedersen a/s designs and manufactures industrial sensors and measurement systems — temperature (RTD and thermocouple) across the widest span, humidity and dewpoint, and vibration and motion for condition monitoring — configured to the individual measuring point across process and manufacturing industries: chemical, glass, paper, plastic, cement, steel, boiler and brickworks plants, and the machine builders and manufacturers who embed sensors in their own equipment.
The right sensor for every process condition
In process and manufacturing industry the sensor is chosen by the conditions of the point — temperature range, pressure, medium and mounting — not by the name of the industry. Instead of a single generic probe, Kjaerulf Pedersen configures the correct sensor for each condition. Start from what the point demands:
| Process condition | What determines the choice | KP sensor |
|---|---|---|
| Standard immersion — pipes, tanks & vessels | Modular RTD or thermocouple, interchangeable insert; type K to ~1150 °C; serviceable via thermowell (replaceable insert on Type A, Type B and BP2) | Type B, Type A, BUI, BP1, BP2, BP2-T |
| High pressure (to 500 bar) / deep immersion | Heavy-wall thermowell; high-pressure sensor | D/DS/DDS + MA-PW D |
| High temperature — furnaces, kilns & boilers | Thermocouple with heat-proof steel or ceramic protection; to ~1700 °C | TC-AM/AMC, TC-BM/BMC, AC/ACC, BC/BCC |
| Confined / bendable routing | Mineral-insulated RTD or thermocouple | RM1, RM3, TM1 |
| Flange / large pipes & tanks | Flange-mounted sensor + flanged thermowell | B-FL + MA-FL |
| Room, surface & ambient | Room and surface housings; IP67 | RR1, RSM |
| Humidity & dewpoint in process / enclosures | Humidity, temperature and dewpoint in one sensor | KPH300 |
| Rotating-equipment health | Vibration — early-stage wear; motion/position; bearing temperature | KPV200, KPM100, RTBC |

Beyond the standard sensor
Beyond the standard sensor, Kjaerulf Pedersen conditions, stabilises and calibrates each measuring point to the demands of the application.
For cold applications, cryo treatment conditions the sensor material so it keeps measuring reliably well below its standard range.
Sensors drift over time, especially under fluctuating heat. Ageing stabilises the sensor for long-term stability and minimum drift — steadier readings and more predictable calibration intervals.
In-house calibration across −33 to +700 °C, plus accredited laboratory calibration from −196 to +1200 °C where it is required.
Condition monitoring: catch developing faults before downtime
Condition monitoring watches the health of rotating equipment — motors, pumps, fans, compressors and gearboxes — so a fault is caught while it is still developing. Vibration is the earliest warning of mechanical wear: it shows an emerging fault at roughly 10% development, against roughly 40% before a temperature alarm and roughly 60% before it becomes audible. Kjaerulf Pedersen develops and builds its own vibration, motion and dewpoint sensors alongside its temperature range — one supplier for temperature and condition monitoring, plug and play into a PLC or SCADA system for predictive maintenance.
Intelligent 3-axis vibration sensor with on-board FFT. Detects early-stage wear in motor, pump, fan and compressor bearings. Modbus or Bluetooth, straight into a PLC.
KPV200 →Measures angle, tilt and acceleration — the position and movement of equipment and structures, complementing vibration on the health picture.

KPH300 →Why manufacturers choose Kjaerulf Pedersen
RTD and thermocouple, from cold applications to high-temperature furnaces, with thermowells for high-pressure and corrosive processes — one supplier for almost any process measuring point, instead of several.
Standard designs, your dimensions: immersion length, process connection, sheath material, cable, plug and output are built to order — from a prototype to a volume run.
Immersion, high-temperature, surface and room temperature; humidity and dewpoint; vibration and motion — developed and built by one manufacturer.
Every sensor is developed and manufactured by Kjaerulf Pedersen — you talk directly to the people who design and build it, not to a reseller.
Frequently asked questions
Should I use an RTD or a thermocouple?
For most process temperatures, Pt100 and Pt1000 RTDs are the standard choice for their accuracy and stability. For the high heat of furnaces, kilns and boilers, thermocouples (usually type K) are used, in a heat-proof or ceramic-protected sheath. The selection guide shows which fits each point.
What temperature range do your sensors cover?
From cold applications through to the high heat of furnaces and kilns. RTDs cover the lower and mid range; ceramic-protected thermocouples handle furnace and kiln heat; and for cold applications, an optional cryo treatment extends a sensor below its standard range. The selection guide lists the range for each sensor family.
Do you supply thermowells, and to what standard?
Yes — weld-in, threaded, barstock and flanged thermowells, built to DIN 43772 — including barstock thermowells machined from solid bar. A thermowell protects the sensor from pressure, flow and corrosion, and lets the measuring insert be replaced without breaking the process seal.
Do you supply material certificates and documentation?
Yes — these are specified with the sensor when you order it: a 3.1 material certificate, a certificate of origin and a certificate of conformity.
Do you supply OEMs and machine builders?
Yes — this is core to our business. We develop and manufacture sensors to your specification for machine builders and manufacturers to embed in their own equipment. Everything is developed and produced in-house, from prototype through to volume, so you work directly with the people who design and build the sensor.
Do you offer condition monitoring as well as temperature sensors?
Yes. Alongside temperature, Kjaerulf Pedersen develops its own vibration (KPV200), motion (KPM100) and humidity/dewpoint (KPH300) sensors for condition monitoring. Vibration gives the earliest warning of mechanical wear on rotating equipment — well before a temperature alarm — so maintenance can be planned rather than forced (predictive maintenance). They plug into a PLC or SCADA system over Modbus.
Can you match or replace a sensor in our existing equipment?
Yes — that is what we do. 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.
What about marine, hygienic or oil & gas requirements?
Those have their own pages. Marine-approved sensors are covered under Marine, hygienic and sanitary designs under Hygienic / Life Science, and offshore and refinery duty under Oil & Gas. This page covers general process and manufacturing industry.
