Pressure sensors
ifm offers a wide range of electronic pressure sensors to meet the requirements of various industrial applications. The ceramic-capacitive measuring cell, tried and tested millions of times, is complemented by a stainless steel measuring cell with thin-film or thick-film wire strain gauges (series PK, PV, PT) and a piezoresistive measuring technique (for pneumatic applications).
All units have robust housings and do not require moving parts such as pistons or springs. The result: The sensors are extremely shock and vibration resistant and operate without any wear or maintenance.
The tried and tested ceramic-capacitive measuring cell is corrosion-resistant and long-term stable. This ensures consistent and long-term accuracy of the measured values. The sensors are resistant to dynamic pressure peaks and guarantee high overload resistance even in the case of extreme pressure peaks that occur for example with fast closing valves.
Units with wire strain gauge in thick-film technology on a stainless steel measuring cell are distinguished by their very compact and robust design. They can be used in almost all industrial areas. The welded stainless steel measuring cell without any seals ensures a high degree of safety, in particular for applications with gas pressures of up to 600 bar as well as in air-conditioning and refrigerating technology where aggressive coolants (freons) are used.

Sensors for acoustic analysis, process- / assembly monitoring, resonance analysis
- Easy mounting of the puck directly on the shaft of the valve actuator
- Various diameters and heights for adaptation to the different drives
- Complete mounting sets for drives from different manufacturers
- High shock and vibration resistance
- Simple installation of the rising stem valve sensor on common valve types

A round target (also known as a 'puck') is used for reliable position feedback of pneumatic quarter-turn actuators or valve plates.
The puck is mounted directly on the actuator shaft. It is equipped with two metal screws that are mounted at different heights and offset by 90°. A dual inductive sensor with two integral sensors detects the upper or the lower metal screw and, thus, the "open" or "closed" position of the valve. The system operates without contact or wear and is self-cleaning. It is virtually resistant to external influence and insensitive to mechanical stress such as vibration and shock.

Mounting adapters allow for installation of the rising stem valve position sensor on valves of various manufacturers.

- Dual inductive sensor for pneumatic actuators and valves
- Designed for simple fit to common actuators based on VDI / VDE 3845
- Quick and easy installation of the AS-i dual sensor
- Position feedback for rising stem valves with up to 80 mm stroke
- Reliable permanent valve monitoring

In industrial processes where liquids, air or gases are used, valves are needed for dosing and control.
Dual inductive sensors provide reliable position feedback for pneumatic valve actuators and valves. They are operated in combination with a switch target (also called 'puck') and detect the "open" and "closed" positions of the valve.
Valve sensors provide position feedback on linear valves. The sensors signal up to three important valve positions to the controller: valve open, valve closed and any position in-between, e.g. for the seat lift.

- Reliable monitoring of liquids and gases in pipes
- Level and limit level monitoring on tanks and containers
- Temperature sensors with high precision over the whole temperature measurement range
- Devices with clearly visible LED display with alternating red-green indication

In industrial processes where liquids, air or gases are used, process sensors serve to measure and detect pressure, temperature, flow and levels.
Pressure sensors are used to detect the system pressure of oil in hydraulic systems or to measure the hydrostatic pressure in tanks and vessels in the food and beverage industry.
Flow sensors monitor the coolant and lubricant supply of machines, power units and industrial furnaces or ensure ventilation of installations and buildings. Electronic level sensors monitor filling levels of liquids or bulk materials in containers, tanks and silos.
In the food, beverage and pharmaceutical industries, temperature sensors are used to ensure that products are at the correct temperature. In machine tool and automotive applications, the temperature or temperature difference measured at drives, gears and motors plays an important role as an indicator of the machine condition. In the steel, metal and glass industries, temperature monitoring of cooling circuits serves to prevent overheating of plants.
Valves are used for dosing and control of liquids, air or gases. Dual inductive sensors provide reliable position feedback for pneumatic valve actuators and valves. Valve sensors provide position feedback on linear valves.

Level sensors
Electronic level sensors monitor filling levels of liquids or bulk materials in containers, tanks and silos. Even critical process conditions such as emptying a hydraulic tank or the unintentional overspill of a tank are monitored using level sensors.
The ifm product range includes units for continuous level measurement or point level detection. Depending on the application, different measuring principles such as capacitive, guided wave radar or hydrostatic level measurement are offered. For non-contact level detection, photoelectric distance sensors or 3D camera systems can be used.
Build-up and wear often lead to failures, in particular if mechanical switches are in contact with the medium. The electronic ifm sensors can do without any mechanical parts or floats. This makes the sensors especially robust and reliable. Further advantages of electronic sensors are the local level indication and easy switch point setting via pushbuttons.

Sensors for mobile machines
- Inclination sensors with CAN or analogue interface
- Inductive sensors with high protection rating
- Pressure sensors with a robust measuring cell for mobile hydraulics
- High shock and vibration resistance
- Wide operating temperature range

In automation technology sensors are the "sense organs" of the control systems. They are also used in mobile machinery and installations. In contrast to devices for industrial automation, the demands on sensors for mobile applications are much higher.
The ifm units are distinguished by a robust housing and high protection rating for use in harsh environments. They are shock and vibration resistant and designed to be used in harsh, dirty environments. The sensors have an extended temperature range so that they can operate reliably in extremely cold conditions and when installed next to hot engines. Moreover, the devices are insensitive to rapid temperature changes. A wide voltage range ensures that even high fluctuations of the on-board system do not affect the function. To comply with the ever increasing EMC requirements in mobile applications the devices feature an increased EMC resistance.
Many sensors have the e1 type approval.
The ifm product range for mobile applications includes inductive sensors, pressure sensors, temperature sensors, inclination sensors and cameras, among others.

In applications where it is not possible to use flow sensors with integrated evaluation, sensors are used in combination with evaluation units. For example, this is the case in hazardous areas, confined spaces or if flow values are to be indicated in a decentralised manner.
The product range comprises evaluation units for control cabinet installation or local mounting. Depending on the unit, it is possible to monitor flow, temperature and/or wire break. All units indicate the flow by means of an LED bar graph.
The evaluation units for local mounting are connected to the flow sensor directly at the measuring point using an M12 connector.
Sensors and evaluation systems are designed and approved for use in hazardous areas according to the applicable directives.
