Compression force measurement up to 320kN

These hydraulic load cells measure and indicate forces directly for a reasonable price. The whole unit (load cell and measuring device) works on the hydraulic principle. Maximum piston stroke is 0.5mm.

In accordance with the surface area of the piston, the force acting on it is transferred to the hydraulic fluid and from there via the connecting pipe to the measuring instrument.

The straightforward realtionship between the pressure, force and piston surface area enables the scale of the measuring instrument to be graduated in a variety of units, e.g. kN, kg, t, m³ or litres.

The piston of this force transmitter is designed to adapt itself to the face of the piston acting on it up to an angle of approx.+- 3°.

For precise conversion of force into pressure the force mustact vertically and centred on the piston which must not be subject to lateral forces.

The load cells are unsuited, or suited only to a limited extent, to the measurement of impact or acceleration. Provided that the frequency is not too high, oscillating forces can also be measured with hydraulic load cells. In such case a measuring unit with a rather large working range is advisable in the interests of prolonging service life.

Chucking power measuring devices made by tecsis are hydraulic force measuring devices that display the measurements in analogue or digital form in combination with measuring and display equipment.

The force measuring devices, which are prepared for static chucking force measurement at self-centring chucks, are extremely accurate.

Chucking force is recorded in a simple, low-cost way in selfcentring chucks using these hydraulic force measuring devices, and directly displayed.

European standard EN 1550 prescribes the use of static chucking force measuring devices in order to make the chucking and chip removal processes safe. All users musten sure that their chucking equipment is operated in accordance with the stipulations of EN 15505 at all times. This includes regular checking of the chucking force using static chucking force measuring devices.

The hydraulic force measuring devices are exclusively intended for measuring static chucking force at rotating chucks. The chucking force measurements must be compared with the target values specified in the operating instructions for the respective chuck. The chucking force loss of chucks at high speeds is determined from the relevant chuck operating instructions.

Force transducer for liquid level measurements; with electrical output

Forces (weights) can be easily and cheaply measured with this hydraulic/electric force transducer and made available directly by means of an analogue output signal for further processing.

The force measuring unit works on the hydraulic principle. The force applied to the piston is converted depending on the piston surface into a hydraulic pressure and transmitted to the integrated measuring cell.

Ring force transducer, Heavy Duty for forces from 4 kN up to 2.500 kN

The load cell in ring form is used for the meaurement on shafts and spindles to which a load cell of standard shape cannot be attached. The distinctive feature of this load cell by comparison with the others is the ring shape of the load cell piston and diaphragm. The force acts on a thrust roller bearing and is transmitted without rotation to the ring shaped piston. In accordance with the surface area of the piston the force acting on it is transferred to the hydraulic fluid and from there via the connecting tube to the measuring instrument. The straight forward relationship between the pressure, force and piston surface area enables the scale of the measuring instrument to be graduated in a variety of units, e.g. kN, kg, t, m3 or litres. Maximum piston stroke is 0.8 mm. The widely differing conditions governing installation, particularly in the case of the ring shaped load cells, will often require different designs of casing and fastenings. In most cases it would be possible to adapt design to customer´s requirements. The measuring devices employed may be pressure gauges, pressure sensors or other pressure measuring devices fitted with contacts.
