Continuous MDU motion data lets operators optimise all three against the sea the ship actually meets. - [Vessel Motion and LNG Boil-Off Gas](https://www.kp-as.com/news/vessel-motion-lng-boil-off-gas/): Updated June 2026. Vessel motion drives LNG boil-off through sloshing. Real-time motion data helps operators cut losses, fuel and emissions. - [Ship Motion Monitoring and Container Loss](https://www.kp-as.com/news/motion-detecting-unit-container-safety/): Updated June 2026. Ship motion drives container loss through parametric and resonance roll. Real-time data helps operators identify and prevent it. - [Vibration Monitoring in Water Treatment](https://www.kp-as.com/news/kpv200-water-treatment/): Updated June 2026. Pressure surges (water hammer), leaks and pump faults leave a signature in vibration — see how the KPV200 detects them at the pump. - [Engine Room Temperature Monitoring](https://www.kp-as.com/news/tempmux-8-case-marine-sensor-solution/): Updated June 2026. In an engine room, trouble shows up as temperature first — the TempMux-8 watches eight points at once to catch hot spots and airflow problems early. - [Temperature Sensors with an Integrated Transmitter](https://www.kp-as.com/news/temperature-sensor-integrated-transmitter/): The 4-20 mA transmitter is built into the sensor itself — no separate transmitter or connection head — in industrial, hygienic and valve-plug versions. - [Measuring Temperature in Small Pipes](https://www.kp-as.com/news/measuring-temperature-in-small-pipes/): Standard pockets rarely fit small hygienic pipes. The in-line thermowell is pre-welded into a short pipe section that orbital-welds straight into the line. ## Pages - [Thermowell Pressure Ratings](https://www.kp-as.com/thermowell-pressure-ratings/): A thermowell pressure rating gives the maximum allowable pressure at a given temperature. The load diagrams on this page show ratings for screw-in and weld-in thermowells, and for the protection tubes of complete temperature sensors, according to material, dimensions and immersion length. Flow limits and maximum tightening torques are included for mechanical selection. - [Thermocouple mV Tables](https://www.kp-as.com/thermocouple-mv-tables/): A thermocouple mV table gives the thermoelectric voltage of a thermocouple in millivolts (mV) at a given temperature according to IEC 60584-1, with the reference junction at 0 °C. A type K thermocouple reads 0.000 mV at 0 °C, 4.096 mV at 100 °C and 41.276 mV at 1,000 °C. - [Home](https://www.kp-as.com/): Kjaerulf Pedersen a/s, Competence Driven Sensor Company — measurement engineered for uptime, data you can act on, and compliance you can document. - [MDU](https://www.kp-as.com/mdu/): Marine › Motion Detecting Unit - [Condition Monitoring](https://www.kp-as.com/condition-monitoring/): Kjaerulf Pedersen a/s · Condition Monitoring - [Compliance](https://www.kp-as.com/declarations-of-compliance/): The declarations and policies of Kjaerulf Pedersen a/s, collected on one page — the current version of each document as a PDF download. These documents are provided to meet regulatory and customer requirements. - [RMA](https://www.kp-as.com/rma/): Returns and claims to Kjaerulf Pedersen a/s go through one form — the claim form in our quality management system. Fill it in, and enclose a copy of the record with the shipment. - [Marine Approvals](https://www.kp-as.com/certificates/): A marine type approval is an official certification from a classification society, confirming that a product type meets the society’s rules for safety, quality and performance in maritime use. For temperature sensors, that means documented performance under the conditions of life at sea: vibration, saltwater, moisture and extreme temperatures. - [Knowledge Center](https://www.kp-as.com/knowledge-center/): Reference guides, standards tables and unit converters for industrial sensor technology — from temperature measurement to vibration, motion and humidity. - [Temperature Transmitter Guide](https://www.kp-as.com/temperature-transmitter-guide/): A temperature transmitter converts the signal from a temperature sensor — the resistance of a Pt100 or the voltage of a thermocouple — into a 4–20 mA current signal that travels long cable runs without losing accuracy. Head-mounted transmitters sit inside the sensor's connection head; rail-mounted transmitters sit on a DIN rail in the control cabinet. - [Pt100 Resistance Table](https://www.kp-as.com/pt100-resistance-table/): A Pt100 resistance table lists the resistance of a platinum RTD at each temperature according to IEC 60751: 100.00 ohm at 0 °C, rising by roughly 0.385 ohm per °C — 138.51 ohm at 100 °C and 18.52 ohm at −200 °C. - [Pt100 Wiring](https://www.kp-as.com/pt100-wiring/): A Pt100 sensor can be connected with two, three or four wires. The 3-wire connection compensates for lead resistance and is the industrial standard; the 4-wire connection eliminates lead resistance entirely and gives the highest accuracy. - [Thermowell Materials](https://www.kp-as.com/thermowell-materials/): A thermowell is a closed-end metal tube that protects a temperature sensor from process pressure, flow and corrosion. Material choice follows the medium: stainless grades such as EN 1.4404 (316L) and EN 1.4571 (316Ti) cover service up to 800 °C, while heat-resisting grades such as AISI 446 and Inconel 600 cover service above 1,000 °C. - [Temperature Sensor Types](https://www.kp-as.com/temperature-sensor-types/): Industrial temperature sensors fall into two main families: platinum resistance thermometers (Pt100), used up to about 600 °C, and thermocouples (types B, E, J, K, N, R, S and T), covering up to 1,700 °C. IEC 60751 defines the accuracy classes for Pt100 sensors; IEC 60584 defines thermocouple tolerances. - [Thermocouple Colour Codes](https://www.kp-as.com/thermocouple-colour-codes/): Thermocouple colour codes identify the thermocouple type (B, E, J, K, N, R, S or T) by the insulation colour of each conductor. The international standard IEC 60584-3 uses a white negative conductor for all types, while the American standard ANSI MC 96.1 uses a red negative conductor. The same colour can mean different things under different standards, so always identify the standard before connecting. - [Contact](https://www.kp-as.com/contact/): When you contact Kjaerulf Pedersen a/s, you reach the people who design and manufacture the sensors.
