HLP190FS (BS) Spring-loaded Linear Sensor

• Stroke lengths from 25 to 150mm
• 19mm body diameter
• Spring loaded shaft with ball anvil fitting
• Flange [FS] or Body clamp [BS] mounting
• Virtually infinite resolution
• Single or dual track option

The HLP190 range of hybrid linear potentiometers provides the facility for single or dual electrical output with a body diameter of only 19mm. Suited to a wide range of industrial applications for medium stroke length requirements – especially structural monitoring data acquisition.

Stroke lengths are from 25mm to 150mm, with a choice of body clamp (BS) or flange (FS) mounting. This model is supplied with a spring-loaded shaft, biased to the fully extended position.

All other models in the HLP190 series (HLP190/SA, HLP190/BC and HLP190/FL models) have been replaced by the SLS190 range.

Hybrid track potentiometers feature a high wiper contact resistance, therefore operational checks should be carried out only in the voltage divider mode. Hybrid track potentiometers should be used only as voltage dividers, with a minimum wiper circuit impedance of 100 x track resistance or 0.5MΩ (whichever is greater). Operation with wiper circuits of lower impedance will degrade the output smoothness and affect the linearity

Electrical output: Single or dual – minimum of 0.5% to 99.5% applied volts
Resolution: Virtually infinite
Hysteresis (repeatability): Less than 0.01mm
Phasing between elements: 0.5mm total in retracted position (multi output units)
Operational temperature °C: –30 to +85
Output smoothness: To MIL-R-39023 grade C 0.1%
Insulation resistance: Greater than 100MΩ at 500Vdc
Operating mode: Voltage divider only – see Circuit Recommendation below
Wiper circuit impedance: Minimum of 100 x track resistance or 0.5MΩ (whichever is greater)
Life at 250mm per second: Typically greater than 100 million operations (50 x 106 cycles) at 25mm stroke length
Shaft velocity maximum m/s: 1
Shaft seal: No seal fitted due to spring loaded probe action.
