Pressure switch is a form of switch that closes an electrical contact when a certain set fluid pressure has been reached on its input. The switch may be designed to make contact either on pressure rise or on pressure fall. Pressure switches are widely used in industry to automatically supervise and control systems that use pressurized fluids.
Pressure Transducers is a device for pressure measurement of gases or liquids. Pressure is an expression of the force required to stop a fluid from expanding, and is usually stated in terms of force per unit area. A pressure sensor usually acts as a transducer; it generates a signal as a function of the pressure imposed. For the purposes of this article, such a signal is electrical.
Pressure sensors are used for control and monitoring in thousands of everyday applications. Pressure sensors can also be used to indirectly measure other variables such as fluid/gas flow, speed, water level, and altitude. Pressure sensors can alternatively be called pressure transducers, pressure transmitters, pressure senders, pressure indicators, piezometers and manometers, among other names.

Pressure Transmitters
AKS 32 & AKS 33 Pressure Transmitter
Highly developed sensor technology means high
pressure regulation accuracy, a very important
factor in the precise and energy-economic capacity regulation of refrigeration plant.
Temperature compensation for LP and HP
pressure transmitters, developed specially for
refrigeration plant:
LP: −30 → +40°C (≤16 bar)
HP: 0 → +80°C (>16 bar)
Compatibility with all refrigerants incl. ammonia means less stock and greater application
flexibility.
Built-in voltage stabiliser, i.e. the AKS pressure
transmitters can be powered from an unregulated voltage supply of any output within
given limits.
Effective protection against moisture means
that the sensor can be mounted in very harsh
environments, e.g. in the suction line encapsulated in an ice block.
Robust construction gives protection against
mechanical influences such as shock, vibration and pressure surge. AKS sensors can be
mounted direct on to the plant.
No adjustment necessary. With the highly developed sensor technology and sealed gauge
principle, the accuracy of the factory setting is
maintained independent of variations in ambient temperature and atmospheric pressure.
This is very important when ensuring evaporating pressure control in air conditioning and
refrigeration applications.

Danfoss 060-110191 Pressure Switch KP 1 Auto -0.2 To 7.5 Bar
Danfoss 060-110191 Pressure Switch KP 1 Auto -0.2 To 7.5 Bar
KP pressure switchs are for use in refrigeration and air conditioning systems to give protection against excessively low suction pressure or excessively high discharge pressure. KP pressure switches are also used for starting and stopping refrigeration compressors and fans on air-cooled condensers. A KP pressure switch can be connected directly to a single-phase AC motor of up to approx. 2 kW or installed in the control circuit of DC motors and large AC motors. KP pressure switches are fitted with a single-pole double-throw (SPDT) switch. The position of the switch is determined by the pressure switch setting and the pressure at the connector. KP pressure switches are available in IP30, IP44 and IP55 enclosures.
