Description
Penny & Giles HLP190 range of hybrid spring-loaded linear position sensor / potentiometers provide the facility for single or dual electrical output with a body diameter of only 19mm.
Features of the HLP190 Linear Position 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All other models in the HLP190 series (HLP190/SA, HLP190/BC and HLP190/FL models) have been replaced by the SLS190 range.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.
The Penny & Giles product range comprises a broad selection of joysticks, sensors and solenoids for use on commercial vehicles and industrial equipment.
The products are the legacy of the Penny & Giles company founded in 1956 and acquired by Curtiss Wright in 2002.
The present-day product range includes: linear and rotary position sensors; LVDT and RVDT transducers; joysticks; studio faders; digital panel meters; and solenoid actuators for a wide range of industrial motion control applications.
Their joystick controls are suitable for commercial vehicle applications for both on- and off-highway use. These include construction and agricultural vehicles, material handling and other specialty vehicles. They are also suitable for use with industrial equipment such as robotics. Their finger-operated joystick controllers are designed for the smooth, precise control of critical functions in a variety of industrial applications where a Human-Machine Interface (HMI) is required. They also have rugged joystick controllers are designed for the more demanding installations found within operator cabs for off-highway vehicles. A wide range of linear position sensors, tilt sensors, rotary sensors, linear displacement transducers and linear potentiometers that offer distinct advantages in reliability, stability and compactness.
