Linear Position Sensor Calibration using SenSet® Field ProgrammabilityAlliance Sensors' LVIT Linear Position Sensors offer SenSet® Field Programmability. SenSet® allows the installer to very simply and quickly exactly match the full scale electrical output of a sensor to the actual mechanical movement range of the device in which the sensor is installed. Quick Start Guide Installation of MR-7 Series In-cylinder Position SensorsMechanical installation: MR-7 in-cylinder position sensors are designed to be inserted into an o-ring port machined into the rear endcap of the hydraulic cylinder. Standard MR-7s use an SAE J1926-1 -8 port with a 3/4-16 UNF thread. Metric threaded versions use an ISO 1649-1 port with a M18 x 1.5 thread. Both ports are Illustrated below. For either size port, the sensor's male thread comes with a Viton o-ring installed. SAE J1926-1 -8 Port
Quick Start Guide ME-7 In-cylinder Position Sensor Installation
Mechanical installation: An ASG ME-7 in-cylinder position sensors is embedded into a 48 mm diameter
cavity in the rear endcap of a hydraulic cylinder. It may be inserted from the front of an unassembled
cylinder or from the rear of a cylinder with a two-piece endcap with a separate end cover.
 What's So Good About LVIT Technology and What Is It All About, Anyway?Alliance Sensors Group, a division of H.G. Schaevitz, LLC, has developed a linear position sensing technology called LVIT that offers an excellent price-to-performance ratio compared to other linear position sensing technologies such as LVDTs, linear potentiometers, and magnetostrictive devices. Furthermore, LVITs can offer the best stroke-to-length ratio of any contactless linear position sensor, because their overall length only increases by a relatively small percentage beyond their stroke. Grounding practice to minimize ground loop issues for sensors with a common I/O groundConcerns about the effects of a common ground on the individual outputs from multiple ASG’s LVIT sensors can be remedied by using a single ground point. This ground point, which should be made at the input ground of electronics used to monitor or measure the sensors’ outputs, is where the power ground/output ground lead for each of the sensors is connected, along with the power supply’s ground. Separate connections are used for each sensor’s power positive and output. By connecting sensors in this manner, variations in the ground currents or output currents of individual sensors are not combined into the outputs of any other sensors in the system. This grounding connection approach obviates the need for isolated outputs and is the universally recommended grounding practice for minimizing ground loop issues. However, if a customer is unable to make the recommended grounding connection, multi-channel isolation modules are available from several sources at relatively low cost per channel. Connecting to Alliance Sensors Group’s current loop output LVIT sensorsAlliance Sensors Group, a div of H G Schaevitz LLC, Moorestown, NJ, USA, makes position sensors utilizing Linear Variable Inductance Transducer (LVIT) technology which offer analog outputs of both voltage and current loop, the most common of which are 0 – 10 Volts DC and 4 – 20 mA DC. A voltage output is typically used in applications that have a receiving device, i.e.: PLC, DAQ system, or readout, located close by so the interconnecting wiring is not very long and can be shielded if necessary to prevent noise or EMI being coupled into the output.
