Technical guides for position, displacement and force sensors

9 technical guides from GUEMISA for choosing, connecting, and installing position, displacement, and force sensors. Each guide explains the measurement principle, the data to compare, and the compatible products.

Choose the sensor

GuideWhat does it answer?
How to measure the position of a hydraulic or pneumatic cylinderIntegrated rod sensor or external sensor: stroke, pressure, output and IP to measure the position of a cylinder, with a comparative table.
Potentiometric, magnetostrictive or LVDT: which one to chooseCompare potentiometric, magnetostrictive, LVDT, and inductive position sensors: principle, wear, stroke, resolution, and output.
Linear position sensor with 4-20 mA output for PLC: how to choose itHow to choose a linear position sensor with 4-20 mA output for PLC: two and three wires, maximum load, 0-10 V and potentiometer with conditioner.
Non-contact angular position (Hall) sensors for mobile machinery: how to choose themNon-contact Hall angle sensors for mobile machinery: Hall versus potentiometer, redundancy, IP69K, EMC, CANopen and J1939 outputs, and multi-turn.
Thread displacement sensor: when to use it and how to choose the strokeWhen to use a thread displacement sensor, which output to choose, speed and acceleration limits, and how to calculate the stroke with margin.

Connect and install

GuideWhat does it answer?
How to connect a linear potentiometer to a PLC: ratiometric vs. 4-20 mAConnecting a linear potentiometer to a PLC: direct to 0-10 V (ratiometric), cursor current ≤ 1 µA and when to use a 4-20 mA conditioner.
What IP rating does a position sensor need for outdoor use or when subject to washing?IP54, IP65, IP67, IP68 and IP69K: what IP rating to order for an outdoor or washable position sensor, and how connector and condensation affect it.

Tests and laboratory

GuideWhat does it answer?
LVDT for laboratory testing: accuracy, stroke and conditionerAmplified or passive LVDT with conditioner: principle, stroke, linearity, spring return or free core and probes for laboratory testing.
Load cells for test benches: types, ranges and mountingHow to choose a load cell for a test bench: types, overload range, mV/V, accuracy, conditioner and moment-free mounting.
