Overview

Pressure switches can be widely used in fields such as petroleum, chemical, metallurgical, power, and water supply to measure and control the gauge pressure and absolute pressure of various gases and liquids. They are ideal intelligent measurement and control instruments for industrial sites. Pressure switches are widely used in the aerospace and military industries, such as the manufacturing of M1A1 tanks, Apollo spacecraft, Boeing 747, Airbus A320, F22, F117 and other products.

Hedeke pressure switch EDS344-3-250-000 in stock

Hedeke pressure switch is a simple pressure control device that can issue an alarm or control signal when the measured pressure reaches the rated value. The working principle of the Hedeke pressure switch is that when the measured pressure exceeds the rated value, the free end of the elastic element produces displacement, which directly or after comparison pushes the switch element, changes the on/off state of the switch element, and achieves the purpose of controlling the measured pressure.

Hedeke pressure switches are widely used in high and low pressure protection control of household, commercial, and automotive refrigeration systems, steam conditions, and power plants; Accumulator, receiver, flash tank, separator, washer, refining unit. It can also be applied to high and low pressure protection control of various equipment and tools. But in the selection of Hedeke pressure switches, the following points should be noted:

1. Number of contacts: one contact (one output) or two contacts (two outputs).

2. Determination of set value and pressure range: It is recommended to set the range between 30% and 65% of the pressure range, and the range can be set between 15% and 90% of the pressure range.

3. The form of connection and disconnection: adjustable or fixed.

4. Whether there is pulsation: If there is pressure pulsation or vibration, a throttle valve needs to be installed to suppress the damage of pulsating pressure to the instrument.

5. In situations with a diaphragm: When measuring corrosiveness, high viscosity, or high temperature, it is necessary to use a diaphragm.

Advantages of Hedeke pressure switch:

1. The core of the product adopts a new type of intelligent microprocessor chip, which has practical and stable functions.

2. LED displays the current pressure or liquid level value;

3. Pressure or liquid level can be set to start or stop according to one's own needs;

4. Four LED products with three units to choose from according to customer needs: Mpa, KG. F/CM2, PSI

5. High and low pressure or liquid level alarm points can be set and output to the control equipment through relays or optocouplers; Output dual relay (single pole double throw) switch quantity;

6. Two relays/two optocouplers/with 4-20mA/0-10V output selectable;

7. Adopting high-precision pressure sensors, with higher accuracy than mechanical pressure switches, less hysteresis, fast response, stable and reliable; Adjusting without dead zone, the relay action pressure point can be set arbitrarily within the entire range;

8. Using buttons to adjust action pressure, easy to use and more flexible; Protection level: IP65, suitable for use in harsh environments;
