EMS40E-1kN (KMM40E-1kN) – Tensometryczny czujnik siły 1 kN ze zintegrowanym wzmacniaczem
Miniature, precise strain gauge sensor for measuring compressive and tensile forces up to 1 kN (~100 kg) with direct voltage output 0.5...4.5 V DC.
The EMS40E-1kN (KMM40E-1kN) model is a compact force transducer made of high quality stainless steel, equipped with an internal measuring amplifier EMS165. Integrated electronics eliminate the need for external signal conditioners, allowing the sensor to be directly connected to standard analog inputs on PLCs, microcontrollers or industrial measurement cards (DAQ).
Key advantages and technological differentiators
Built-in signal amplifier (EMS165): Voltage output 0.5...4.5 V eliminates interference of low-level bridge signals and reduces the cost of the entire measurement system.
Bidirectional measurement (Squeeze / Stretch): Factory zero offset at 2.5 V DC allows precise identification of the direction and force vector (nominal signal $pm 2 ext{ V}$).
High precision: Low non-linearity of only $le 0.25\%$ F.S. gwarantuje wiarygodność pomiarów w aplikacjach laboratoryjnych oraz przemysłowych.
Low-profile stainless steel construction: Durable, miniature bridge housing allows installation in limited space of machines and robot arms.
Convenient 5 V DC power supply: The possibility of direct power supply from the USB bus facilitates the construction of mobile and portable diagnostic stations.
Typical applications and application areas
Robotics and end effectors: Pressure force control, monitoring of Cartesian robot grippers and industrial arms.
Assembly presses and clamping stations: Real-time monitoring of the pressing process of bearings, bushings, and destructive tests.
Quality control and laboratory tests: R&D research stations, durability tests of plastic and electronic components.
Medical equipment and rehabilitation systems: Precise measurement of pressure and static/dynamic loads.
Engineering tips and good installation practices
Elimination of lateral forces and bending moments: The EMS40E strain gauge should be mounted axially. The use of ball joints or fork tips prevents the occurrence of torsional and shear stresses that distort the measurement result.

Frequently asked questions (FAQ)
1. What is the difference between the EMS40E model and the standard EMS40?
The basic version (EMS40) generates a raw signal from a strain gauge bridge ($1.5 ext{ mV/V}$) i wymaga zewnętrznego wzmacniacza (np. WDT11 lub MD150T). Wersja EMS40E posiada zintegrowany wewnątrz obudowy wzmacniacz i podaje gotowy sygnał napięciowy 0,5...4,5 V.
2. How to interpret the output voltage in bidirectional measurement?
For the idle state (no load), the signal is exactly 2.5 V. When compressed, the voltage increases linearly to 4.5 V, while when stretched it drops to 0.5 V.
3. Are other measurement ranges available in this series?
Yes, the EMS40E / KMM40E series includes the variants: 1 kN, 2 kN, 5 kN (with a linearity tolerance of 0.25%) and 10 kN, 20 kN and 50 kN (with a linearity tolerance of 0.5%).
