Basics Special Sensors
Basic Knowledge of Special Sensors
Inclination sensors determine the absolute discrepancy in relation to the gravitation (measuring range based on: g=9,811 m/s², 50° northern latitude NN). Beside analogue inclination sensors, this product group covers the latest generation with CAN-Open-connection, digital AC switching output for direct control of hydraulic valves or biaxial versions. The modular housing design allows either the use of JPT or of M12 connectors as well as fixed cable versions.
PULSOTRONIC inclination sensors are available for measuring all 3 axis: X - Y - Z:

Acceleration sensors are measuring the inertial force that has an effect on the body and belongs to the group of inertial sensors. Pulsotronic's acceleration sensors are using MEMS (micro-electronic-mechanical system) as interactive element. Identical in construction to the group of inclination sensors, the acceleration sensor is offering the analysis as analogue, digital or BUS signal.

Based by Hall-function angle sensors of KW-types from PULSOTRONIC are detecting angle rotations up to 360°. Advantage of this sensor family is the splitting between sensor and magnet. With this angle sensor are working in applications with tolerances. Deviations at axial, vertical and tumbling are possible in limited values. Depends on the material of the magnet angle sensors can detect them with a distance of some Millimeters in an extended temperature range between -40°C to +80°C. Available output signals are: analog current or voltage, PWM, SPI or CANOpen.

Works on piezo-electric basis. A special broadband acoustic receiver is recording body sound attenuated signals. Depending on the application, Pulsotronic is adjusting an adapted frequency band via internal filters. The kind and intensity of the noise plays a decisive role. To guarantee a secure function, it is necessary to have a signal-noise-distance of 5dB. The customer has the possibility to regulate the switching threshold of the sensor via potentiometer. Operation area:
Speed monitors are restricting electronically the rpm of the rotor or the gear upwards or downwards. Depending on the version, the rpm restriction is adjustable with a potentiometer or electronically with micro controllers. Operation area:
Inductive temperature resistant sensors are suitable for the use in extended temperature areas of 40°C up to 100°C

Inductive sensors with closed stainless steel front are working with a special tuned oscillator frequency and fading out the housing material. By doing so, these sensors detect all ferromagnetic materials and are usable in the classical machine-building applications.

Pickup sensors consist of only one special highly sensitive coil, mostly with multiple ferrites. The analogue signal of a pickup sensor is processed in external switching amplifier.

The quad sensor is equiped with four active areas. By the help of tuned oscillator frequencies, the sensor head detects four targets that are next to each other without mutual influence.
