TEMPERATURE SWITCHES AND SENSORS
TEMPERATURE SWITCHES AND SENSORS
BEDIA Motorentechnik specializes in developing, producing, and distributing solutions for level and temperature monitoring, focusing on extreme conditions. They provide customized solutions for industries such as agriculture, construction, and utility vehicles. The company is ISO 9001:2015 and ISO 14001:2015 certified, ensuring high-quality standards.
These switches feature reset hysteresis of ≤ 15 K and ≤ 25 K, operating with a bimetal disc that snaps at a nominal switching temperature from -25°C to 190°C. Available in normally open or closed configurations, they reset automatically when the temperature drops. Housed in brass or stainless steel, they are robust and reliable.

Various connector types and designs are listed, including blade terminals, bayonet connectors, minitimer connectors, and DEUTSCH connectors, each with specific protection classes and configurations.
Detailed order numbers for different configurations of bimetal temperature switches are provided, specifying thread/HEX sizes, switch points, hysteresis, and electric potential.
These switches use a Pt1000 thin-film resistor in a bridge circuit, offering precise switch point tolerances and quick response. Available with low-side, high-side, or potential-free DC switching outputs, they have a nominal voltage of 12 VDC / 24 VDC, an operating temperature range of -40°C to +125°C, and a maximum switching current of 1 A.
These sensors measure liquid temperatures using a Pt1000 precision resistor. The output voltage is temperature-dependent and nearly linear, ranging from 0.5 V to 10 V. They are overload-proof and short-circuit-proof, with no mechanical moving parts.
Used for temperature measurement in various applications, including commercial vehicles and biogas plants, these resistors are available with different sensor types like Pt100, Pt500, Pt1000, Ni100, Ni1000, and KTY silicon sensors. Optimal thermal coupling is emphasized for accurate measurements.
These sensors offer fast response times, excellent long-term stability, and low self-heating, making them suitable for various industrial applications.
KTY sensors are cost-effective alternatives to Pt sensors, with a positive temperature coefficient and a non-linear characteristic, suitable where non-linear characteristics are acceptable.
NTC thermistors are suitable for monitoring resistance over a wide temperature range, with a negative temperature coefficient, used where non-linear behavior is acceptable.
Basic values for platinum and nickel sensor elements are provided, detailing resistance at various temperatures, essential for understanding sensor performance under different conditions.
- Temperature Sensors: Multiple sensors with different thread sizes, sensing elements (Pt100, Pt1000, KTY, NTC, Ni1000), and temperature ranges from -50°C to 250°C, available in 2-wire and 4-wire configurations.
- Connection Types: Various connection modes, including screw-in resistors and connectors like bayonet, Packard, and minitimer.
- Materials: Some sensors feature stainless steel housing and are thermally decoupled for enhanced performance.
- Cables: Ready-made cables with bayonet connectors according to ISO 15170, available in different lengths (300 mm to 6000 mm) and configurations (straight and 90° angle).
- Connectors: Various connectors offered, including female bayonet connectors and 4-pin bayonet connectors for corrugated tubing and cables.
Each product is identified by an order number, specifying the mode of connection, temperature range, sensing element, and thread/HEX size. A comprehensive order number overview is provided for easy reference.

In a robust brass or stainless steel housing there is a bimetal disc, which snaps over when nominal switching temperature is reached. The switching contact can be implemented as a normally closed contact or a normally open contact in the temperature range between -25°C and 190°C. The switch opens or closes its contact upon rising temperature and resets automatically to the original switching state when the temperature has dropped. The switching temperature cannot be adjusted. The bimetal disc carries no current, and this eliminates the possibility of arcing. The reset switching temperature is...

These temperature switches operate by means of a thermally sensitive bimetal snap-element which switches a double electrical contact when reaching a pre-set response temperature. They can be normally open or normally closed. The electrical current flows through the bimetal element, which therefore gives a combination of temperature- and current-sensitivity. The resilient snap action disk ensures excellent performance. The bimetal will only snap back to its initial condition after the temperature has dropped significantly. Compared to other temperature switches with relatively small hysteresis,...
