Linear potentiometer are well known displacement transducers. The working principle is a voltage division on a hybride conductive film. It is possible to get different housing and mounting types, like versions for hydraulic cylinders with spherical, clamping jaw mounting or sprung loaded. The first linear potentiometer with a protection class of IP 68 and contactless measurement systems. The LMI- series constitutes a new generation of L. P. A ring magnet leads the transducer contactless in the inside of the sensor. Therefore a cyclenumber of over 100 Mio. is avieable without problems. Against traditional systems this series mutes additional vibrations over the contactless ring magnet. A well designed and inexpensive measurement system that will be established in the market very quickly.

The semiconductive reluctance elemental device (single crystal InSb) of high sensitivity was designed for the noncontact potentiometers.
Excellent characteristics by matching with the magnetic circuitry are exhibited.
There is the following advantage because it is the contact-less structure that a magnet was combined with the reluctance elemental device unlike slide wire potentiometer.
- Long life time because a resistor isn't worn away.
- Low torque because a shaft is held by the ball bearing.
- Mechanical response is excellent and electric response exceeds the mechanical response fully.
The angle detection of ± 50° is possible.
LP05M series is suitable for the high reliability use because a temperature compensation circuit is built in.
THose potentiometer are used for :
- Paper thickness measurement for ATM and OCR.
- String tension or Tape tension controller

Compact and accurate control potentiometer with digital display replaces traditional machine potentiometers.
The Accu-Dial is a compact, versatile, and precise micro-controller-based 10-turn potentiometer with an LCD set point display for accurate visual confirmation. Electro-Sensors' Accu-Dial enters the next generation of control products that allow you to precisely monitor and control any application currently using a potentiometer. It replaces conventional single-turn and multi-turn potentiometers in applications such as control of AC/DC variable speed motor drives, temperature control, hydraulic systems, pneumatic systems, or any other system currently using a potentiometer.
The Accu-Dial is quick and easy to install. It mounts through the same hole as a potentiometer, and has the same three-wire connection as the potentiometers it replaces. A precise 10-turn potentiometer with robust turning knob gives the operator a familiar feel and reduces mechanical set point movement in high vibration environments.
Features:
- Accurate visual confirmation of set points in user-defined units assures repeatability across operators.
- LCD display assures accuracy, reduces waste materials, and saves money.
- Quick and easy installation with simple calibration and setup ensures minimal machine downtime and process setup.
- EEPROM protection retains programming and calibration in the event of power failure.
- Robust turning knob engineered for precision and strength with a familiar feel.
- Housed in a tough ABS plastic enclosure - NEMA 4 rated.

SMP9210/9211/9212 Dual 10-Bit Nonvolatile DAC
INTRODUCTION
The SMP9210, -11, -12 family consists of serial input, voltage output, dual 10-bit (1024 steps) digital-to-analog converters. The devices will recall any Dac output voltage on power up and can operate from a single +2.7V to +5.5V supply. The maximum output Temperature Coefficient (Tc) of ±25ppm/0C make them ideal for high accuracy and temperature stable calibration purposes. Internal precision buffers swing rail-to-rail with an input reference range from ground to the positive supply.
The parts integrate two 10-bit DACs and their associated circuits: an enhanced unity gain operational output amplifier, a 10-bit volatile data latch, a 10-bit nonvolatile data register and the I2C compatible 2-wire serial interface.
The SMP9210 has a Chip Select input to enable/disable communication with the device, the SMP9211 has a Mute input to turn the outputs off and the SMP9212 has a reference voltage output.
Programming of the configuration, control and calibration values by the user is simplified with the interface adapter and Windows GUI software obtainable from Summit Microelectronics.
