Inductive sensors

Robust and sensitive at the same time


Inductive sensors

Inductive proximity switches are ideal for non-contact detection of metal objects. A metal object that is located in the sensing region of the proximity switch, the electromagnetic field is changed, leading to a switching signal. Positions of metal objects or machine parts can be safely andwearare detected. The great advantage of the inductive proximity switch is in its almost full immunityagainst water and dirt .


Our Proxi-Teach® Technology provides safe operation under all conditions. Sensors with extremely high switching distance allow metal detecting even where conventional standard sensors are overwhelmed. Inductive proximity switches Proxitron therefore find themselves in a variety of applications in the production of steel and metal processing industries and are used by many plant and machinery farmers preferred"when things get hot" . In addition to the wide range of industry standard solutions for complex applications, we offer customized versions up to the individual single solution .

Capacitive sensors

Made object detection easily


Capacitive sensors

Capacitive proximity switches are the all-rounder when it comes to the detection of non-metallic materials. An electric field generated by the sensor is altered by the proximity of conductive materials, thus causing a detection of objects in the detection area of ​​the sensor. Thus, a variety of materials such as wood, flour, plastic pellets, coffee, sand or liquids such as oil, water and milk can be reliably detected. The more the material is able to conduct electric current, the better the detection capability is through the capacitive sensor.

A particular advantage of the capacitive sensors is to detect through the ability of these substances by non-metallic materials. This allows, for example, the level monitoring of liquids or granules in plastic or glass containers without the sensor having to delektierenden the material must come into contact. Proxitron offers a wide range of capacitive sensors for different applications in industry and research. This includes versions with high switching distances or for increased ambient temperatures. We also offer special designs for the analog level monitoring with teach-in technology that provides a fast adaptation to different operating conditions.

Various housing materials, connections or operating voltage variants round off the program.

Functions and applications of Proxitron flow sensors

Flow sensors Proxitron can monitor the flow rate of liquid or gaseous media, enabling a simple and effective control of flow processes. Basis of this sensor system is the calorimetric principle.Similar to the cold feel of a finger in the wind, the cooling of a surface is used by a medium flowing past. With a flow sensor, the sensor surface is heated to a defined temperature. If this surface is exposed to a flow, the Senor surface cools. A greater flow leads to a greater cooling and serves as a measure for the flow speed. The cooling effect of the flow is electronically evaluated and the flow sensor supplies depending on model a hereupon based output signal, which can be used for flow monitoring. The applications of flow sensors are diverse, ranging from the general air conditioning systems, exhaust systems, to monitoring of cooling and lubricant circuits. In contrast to the indirect flow control by controlling the rotational movement of a fan or pump, is on this principle directly controls the flow of the medium and thus enables the detection of dirty filters and blockages or blockages in the flow circuit. The adjustable flow value can be an early warning of falling below a minimum flow supply and so z. B. initiate timely maintenance of air conditioning. Due to an absolutely maintenance-free and wear-free operation Proxitron flow sensors in comparison with other sensor systems such as wind vanes and vane anemometers relays are superior and are preferably used where safe and trouble-free flow control is required.


flow sensors

The construction of the sensors in a seamless closed housing predestined these particularly suitable for use in environments withhigh contamination levels . Proxitron Air flow sensors (air flow monitor) in solid plastic housing are everywhere at home, where aggressive chemical atmospheres prevail. They resist even containing sulfuric exhaust of electroplating bathswork and many years of trouble free. flow sensors Proxitron are available in various designs. In principle, between sensors for monitoring gaseous and liquid media distinguished.

flow sensors

Flow sensors for gases (also called air flow monitor) are in most cases provided with a compact plastic housing that the easy installation allows in existing exhaust ventilation or ventilation systems. The Flow sensors for liquids have stainless steel process connections in the common pipe thread sizes. Available in both cases variants for AC or DC operating voltage , with different switching output types or with analog output . The units are delivered with a fixed connection cables of different lengths or with conventional M12 connector. Proxitron flow sensors are also characterized by their ease of use from. On push of a button , the sensor will detect the existing flow and represents the flow limit so that a stall is detected. This has diverse applications in different industries, but also in the HVAC and building automation. A matching accessories completes the program and also allows for the flameproof installation of the sensors. Wherever a powerful, yet cost-effective solution is required for flow monitoring, we provide you with our know-how.
