Miniature<br>button force sensor

button force sensor


Area: 0.5 - 50 kN
Size: Ø 50 x 25 mm
Notes: with force application knob


Button force sensor for measuring compressive forces in the range of 0.5 – 50 kN. Size Ø 50 x 25 mm. Stainless steel housing according to protection class IP65.

The load cell X-138-S is suitable for universal use in industrial force monitoring applications. The force sensors are integrated directly in the force flow and measure precisely in the range of 0.5 – 50 kN.

The space-saving design has a size of Ø 50 x 25 mm. The load cell comes in a solid stainless steel housing with a tight design according to protection class IP65. This guarantees trouble-free operation, even under challenging environmental conditions. The force application takes place centrically and is carried out via the spherical force application knob (button).


  • 4x M4 threaded holes on the underside for easy mounting
  • With force introduction button for force introduction
  • Encapsulated version IP65
  • Measuring ranges from 500 N to 50 kN available

Electrical connection

The force sensors from X-Sensors are based on a strain gauge full bridge with strain gauges. The output signal for this sensor is specified in mV/V. Various input modules of controllers already allow the direct connection of force sensors with strain gauge full bridge.

Additionally, measuring amplifiers with voltage output (0-10 V) and current output (4-20 mA) are available, which amplify the strain gauge full bridges accordingly. The measuring amplifiers are available in a robust field housing or for DIN rail mounting. Brand new is the compact inline amplifier X-201-IN09 from X-Sensors, which can be used universally for static and cyclic measurements and offers an excellent price-performance ratio.

Mechanical connection / design

The advantages of button compression force sensors are the easy mounting and the precise force application via the sensor. This type of force sensor is suitable whenever compressive force is to be measured. The flat design of the load cell has the perfect characteristics for installation in confined spaces. The various load cells are universally applicable and are used in the fields of measuring and testing technology, industrial process control, press-in force measurement, machine control, special machine construction, tool construction, and machine condition monitoring.

The mounting of the force sensors with spherical load introduction knob is fast and uncomplicated. The sensor is screwed on from below on one side and then measures the force acting on the button. A custom version for screwing from above is available. The surface on which the force sensor is mounted must be flat and sufficiently rigid to not deform during loading.
