Honeywell linear and rotary potentiometers measure linear, rotary position or displacement. Use a tried and true potentiometric technology originally developed for military applications and more recently applied to industrial markets. The proprietary MystR® conductive plastic has extensive temperature range, infinite resolution and provides absolute position measurement on power-up. Intermediate signal conditioning is not required for normal ratiometric position sensing. Very small stroke units (5 mm [0.2 in]), and units required to withstand exposure to harsh chemicals, function immersed in different oils or water, are available.
Best Used For:
Applications requiring sensing response to the movement or location of a target, such as a molding press slide or a pulley shaft.

IGP Series
Using this potentiometer a maximum angular rotation of 3800° can be converted into a voltage proportional to the angle of rotation, through the medium of a conductive-plastic potentiometer.
This special "heavy-duty" version is designed to measure angular or linear displacement under the most difficult of enviromentat conditions. Simply yet robustly built, these units are suitable for use in all manner of industrial applications and engineering industry.
The cast housing is watertight. The single stage gearing is exceptionally backlash-free. Heavy-duty bearings allow for high axial loading on the shaft; gearwheels or even chain drives may be used directly drive the shaft.
Sealing is achieved through the use of a stepped bush whilst electrical connections are made via plug and socket mounted on the side of the unit.
Special features
- reduction gearing 3:1, 5:1, 10:1
- good linearity 0.1 % (standard)
- long life typically 100 x 106 movements
- mechanical rotation
- robust construction with 10 mm shaft
- Protection class IP 65

The Varior Potentiometer foot switch was designed as a low cost foot control where a non-watertight housing is suitable. Four standard prewired 2 Watt linear models are available. The momentary models have a spring return pedal action, and the maintained models have adjustable friction pads. Maximum resistance must be specified when ordering. The foot switch has a drawn steel housing with black cover, complete with full treadle pad and nonskid base pad.
Also available in our heavy duty Hercules housing:
HERCULES POTENTIOMETER FOOT CONTROL
Environmental Ratings:
NEMA Type 1, 2, 4 & 13
Driptight - Dusttight - Watertight - Oiltight
EN 60529 Degree of Protection IP56
This foot switch is designed for use with variable speed motor drives and is available in selected 2 watt linear values. Specify the maximum resistance you want. Depressing the treadle rotates the potentiometer from zero to the selected maximum resistance shown below. By wiring to the third terminal it goes from the maximum resistance to zero. The treadle is spring loaded and returns to the normal position when the foot pressure is removed. A SPDT auxiliary switch contact rated at 15 Amps 125-250 VAC can be added to the control. The auxiliary switch will operate at the beginning of the treadle stroke. On special order, up to 3 SPDT switches can be added and adjusted for operation at any point of the treadle stroke. Details on switch size, weight, full shields and construction are the same as for the Hercules foot switches. "OX" Shield available

Titrando %u2013 touch the future
Titrimetry - one of the oldest analytical methods - has lost none of its relevance despite the introduction of many analytical methods. This is due not only to the unique advantages offered by the titration method but also to the advanced development in instrumental titrimetry.
The Metrohm titrator family Titrando offers state-of-the-art technology for modern laboratories. It is entirely oriented towards quality control of management in the laboratory and offers control of the rights of access and complete traceability up to the 'calibration history' of the sensors. It meets the requirement of GLP/GMP and 21 CFR Part 11.
Operating the Titrando System is simple and intuitive. No matter whether you operate the Titrando with the Touch Control or via a PC and a mouse - both appearance and operation are practically identical. The system's operator guidance can be regarded as exemplary.
The Titrando system expands to meet your requirements:
The basic unit consists of a Titrando with one measuring interface. This basic unit can be extended to form a super-titrator that controls up to 12 burets and boasts 6 galvanically separated measuring interfaces.
