Class of accuracy
Devices (e.g. measuring instrument or measuring devices ) on which the error and also the effects in defined test conditions are within defined limits; they can have a class identifier that mostly cor
Counter flow cooling
Normal cooling principle on water-cooled oil coolers. It states that the medium to be cooled flows in the cooling pipes in the cooler in the opposite direction to the cooling water.
Back pressure
Pressure that acts against a force or another pressure over an area (according to DIN 24 312).
Large signal range
Operating range of a continuously adjustable valve with high performance, i.e. more than 50 % of I nom, as is necessary for moving to a point or reversing the direction. Opposite: Small signal range
Limit switch
On reaching a set pressure these switches actuate a normally open or normally closed contact. Limit switches are predominantly installed in pressure gauges ( Contact pressure gauge ). A differentiatio
Limit signal
Binary output signal from a limit monitor (DIN 19 237).
Limit monitor
Compares the value of an input variable with a limit. If this limit is exceeded or dropped below, the limit signal changes (DIN 19 237).
Limit load control
The limit load control has the task of making it possible to fully exploit the power from a drive motor, even if additional loads are activated and the sum of the power demanded by all loads would exc
Frequency limit
Highest frequency of a periodic signal at which the signal is still just processed without errors. Frequency limit of a signal component : Inverse of the sum of the minimum pulse duration and the mini
