Blade25 Linear Position Sensor - Multiple Output Modes

Blade25 Linear Position Sensor
Multiple Output Modes

The Blade25 is a non-contact inductive position transducer capable of monitoring up to 25mm of linear travel or 90° of rotation.

The Blade25 Position Transducer is a solid-state device, using induction technology to monitor the position of a metallic object ('activator') that is mounted to or machined as part of the moving part of the application.

With a constant air gap between the moving part and the position transducer, mechanical wear of the transducer is eliminated providing excellent long-term reliability even in the most extreme operating environments.
The Blade25 position transducer houses two inductive coils that determine the position of the metallic activator, and has been designed to allow measurement of both linear (up to 25mm) and angular rotation (up to 90° approx) position. It is also possible to monitor non-uniform movement provided that the movement is repeatable.

The position transducer is supplied with 'BladeCOM' calibration software to allow simple reconfiguration of the device. The operational range, switch points, output modes and other advanced parameters can be set from within the software, with the sensor functionality shown via a real-time monitoring and diagnostics display.

• Suitable for Linear (25mm), Angular (90º) or Non-Uniform Position Monitoring
• IP67 Protected - Suitable for Submersion
• Suitable for dusty, moist and high vibration environments
• Not susceptible to presence of magnetic fields
• Multiple Output Modes - Analogue; PWM; Serial; Switch
• Free BladeCOM Configuration Software
• Excellent Long-term reliability (unmatched by contacting potentiometers,
LVDTs etc)
   
 

Blade60 Linear Position Sensor - Multiple Output Modes

Blade60 Linear Position Sensor
Multiple Output Modes

Blade60 is a solid-state inductive position sensor with a configurable 60mm measurement zone, capable of monitoring linear and shallow-arc movement.

Blade60 is a fully programmable Inductive Position Sensor, capable of monitoring both linear and angular movement. The sensor is completely non-contact, using the latest induction technology to detect the position of a metallic object (often referred to as the 'activator') which is either attached to the moving part or machined into it.
The sensor has a 60mm zone in which the position measurement can be made. It is possible to monitor linear (up to 60mm), angular (up to 90° approx) and even non-uniform repeatable movement within this measurement zone. The measurement range limits can be re-programmed via our free BladeCOM software, so the full-scale output can be achieved over a smaller measurement range if required. For example the sensor can be programmed to provide a 0.25-4.2V output over just 30mm of the measurement zone.
The non-contact nature of this inductive position sensor ensures long-term reliability in dusty, abrasive, high vibration, moist and other harsh operating conditions. Unlike hall-effect devices, the inductive technology used ensures the sensor output will not drift with temperature and is unaffected by changing magnetic fields in the application.

Environmentally protected to IP67, the Blade60 Inductive Position Sensor is suitable for fully submerged installations and applications subject to salt spray or regular jet washing. The materials used are compatible with most aggressive industrial and automotive fluids, so mounting fully submerged within a vehicle transmission, for example, is possible.

• 60mm measurement zone capable of 60mm linear and 90º angular measurement
• Fully sealed and can be installed submerged
• No contact with moving part - excellent long-term reliability
• Compatible with most automotive fluids (engine & transmission oil etc)
• Compact design for simple installation
• Unaffected by presence of magnetic fields.
   
 

Dual Cavity Linear Position Sensor - 0-4.2V Single/Dual Sensor

Dual Cavity Linear Position Sensor
0-4.2V Single/Dual Sensor

Non-contact displacement transducer capable of monitoring linear and angular movement, with the range determined by the shape of the target 'activator'

Dual Cavity is a unique non-contact displacement transducer that uses induction technology to detect the presence of a metallic object ('activator') within each of the transducer's two open sensing holes.
This unique arrangement allows for a wide range of linear or angular motion to be monitored and various output characteristics to be generated simply by changing the shape of the activator.
The Dual Cavity displacement transducer's analogue output varies symmetrically about 2.5 Volts - the output level with no activator present. This 2.5V is termed the "output reference voltage" and the nature and extent of variation from this reference level depends on the design and material of the activator. As standard this displacement transducer suits a total movement of 30 to 50mm travel at the sensing holes to get full-scale output with a good linear response.

The two sensing holes have opposite effects. Introducing an activator into the positive hole sends the level up from 2.5V, and into the negative hole down from 2.5V. This arrangement is extremely flexible, allowing a range of response characteristics to suit many applications. Good linearity can be obtained where required, and various types of non-linear behaviour can also be generated. For linear behaviour the activator arms are typically tapered and symmetrical.

• Suited to linear and angular measurement - output characteristics determined by activator shape and materials
• Environmentally protected to IP67 - Suitable for full submersion
• Perfect for dusty, high vibration, high temperature and moist environments
• Low cost - well suited to high volume OEM applications
• No contact with moving part(s) - excellent reliability
   
 

Through-hole Linear Position Sensor - Multiple Output Modes

Through-hole Linear Position Sensor
Multiple Output Modes

The through-hole position sensor was originally custom-developed to monitor brake pad wear on a military land vehicle. A small cylindrical metallic target, referred to as the 'activator', is mounted to the brake pad assembly and moves within the sensor's open sensing hole as the brake pad wears. Brake pad wear data provided by the sensor is fed back to the vehicle ECU in real time, helping to improve vision of current vehicle condition and maintenance requirements.


A design adaptation of the custom rod position sensor, this sensor is capable of monitoring up to 12mm of linear movement within the open sensing hole. The sensor is a 10 bit device and offers extremely high resolution over the 12mm measurement range. With no moving parts and environmental protection to IP67 the sensor is very well suited to brake applications where dust, grime, high temperatures and thermal shock are often factors.
This sensor is available for purchase in its current form in low quantities, however volume manufacture is possible for OEM applications. Please contact us for more informtion.

Rod Linear Position Sensor
Multiple Output Modes

The Rod Position Sensor was originally custom-developed to monitor the height and movement of a series of moveable aero struts on a Formula 1 car.


A cylindrical tinned steel target, referred to as the 'activator', is mounted to each aero strut, directly in-line with the sensor's blind sensing cavity. As the aero parts move, the activator enters the sensing cavity allowing the sensor to produce an output relative to absolute position.

The rod position sensor is ideal for other applications in which a very small amount of linear movement needs to be monitored. The sensor has a low height profile and no internal moving parts, with no physical contact between the sensor and the moving target 'activator'. The total measurement range of this sensor is 8mm, which is fully configurable via the supplied configuration software.

This sensor is available for purchase in its current form in low quantities, however volume manufacture is possible for OEM applications. Please contact us for more informtion.
