INTRODUCTION The draw wire sensors of the mobile hydraulic series MH were specially developed for the demanding area of construction machines and construction equipment. The sensor can be individually configured depending on the application, in which it is used. Small adhesive and abrasive particles with small grain size can easily be removed when using the open MH versions. Seawater resistant protective grating provide a maximum protection against larger foreign objects like tree branches. In case of applications with high safety requirements, thicker stainlesssteel wire ropes are available,...

OPTIONS The following table gives an overview of frequently used options, with which the standard sensors can be equipped. Option Improved linearity (not in combination with S1 or S2; further restriction see page 3) Inverted output signal (only analog output) Description Improved linearity 0.1 % (L10) or 0.25 % (L25) The analog signal of the sensor is increasing by extracting the rope (standard). Option IN inverts the signal, i.e. the signal of the sensor declines by extracting the rope. range retracted Redundant output signal Changed rope outlet (only in combination with C1 or C3) By using a...

Draw wire sensors with the analogue output versions 5VT and 10VT are equipped with teachable, internal electronics, called VT-Electronics. The signals provided by the sensor's potentiometer are digitized by the VT-Electronics. This digital information is first processed by the electronics, then transformed back and given out as an analogue output signal 0 to 5 V or 0 to 10 V. The digitization offers two possibilities of adjustment, by which the sensor can be configured individually using the Squeezer: 1. Teaching of the measurement range. After a successful teaching process, the squeezer can...

Single analog signal WARNING NOTICES • Do not let the rope snap back. If the rope is retracted freely, this may lead to injuries (whiplash effect) and the device may be damaged. • Caution when unhooking and retracting the rope into the sensor. • Never exceed the specified measurement range when extracting the rope! • Do not try to open the device. The stored energy of the spring drive may lead to injuries when being mishandled. • Do not touch the rope when operating the sensor. • Avoid guiding the rope over edges or corners. Use a deflection pulley instead. • Do not operate the sensor if the...
