Overview

The ITT pressure switch/zero pressure switch 131P12C3SZ in the United States adopts high-precision and high stability pressure sensors and transmission circuits, and then uses dedicated CPU modular signal processing technology to achieve the detection, display, alarm, and control signal output of medium pressure signals.

Product Details

ITT pressure switch/zero pressure switch from the United StatesThe main categories of 131P12C3SZ include normally open and normally closed. The main features are:

1. Adopting the British style pipe thread quick connector or copper pipe welding installation structure, the installation is flexible, easy to use, and does not require special installation and fixation.

2. The plug-in wire type connection can be freely selected by users.

3. Sealed stainless steel sensor is safe and reliable.

4. Manufacturing can be carried out within the pressure range according to the pressure value selected by the user.

ITT pressure switch/zero pressure switch from the United StatesIt is a device combined with an electrical switch that activates the switch contacts when the pre-set fluid pressure is reached. It is mainly used for outputting alarm or control signals on industrial equipment such as power plants, petrochemicals, and metallurgy industries. It has important applications in the industrial field and can prevent damage to important devices in production engineering, avoiding major production accidents.

Main sensitive components of pressure switch 2.1 Bellows

Features: It has better durability and vibration resistance than Bourdon tubes, with a large adjustable range of connection difference. The main materials are stainless steel, phosphor bronze, etc. The price is relatively high, but the measurable pressure range is small, with a diaphragm of 40MPa (CB33) 2.2.

Range: -100Kpa to 200MPa

Power supply voltage: 12~35V DC (24V DC calibration voltage)/AC 220V AC power supply

Output relay capacity: 380V 3A, 220V 5A, 24V DC 5A, etc

Accuracy: better than various parameters such as 0.0.5% FS and 1% FS

Setting range: Full range range range can be set

Sampling rate: 10 times/second (customizable speed according to customer needs)

Interface thread: M20 * 1.5, G1/4, G1/2, 1/4NPT (can be customized according to customer needs)

The working principle of a pressure switch is that when the pressure inside the system is higher or lower than the rated safety pressure, the disc inside the sensor instantaneously moves, and the switch joint is connected or disconnected by the connecting guide rod. When the pressure drops to or rises to the rated recovery value, the disc instantly resets, and the switch automatically resets. In other words, when the measured pressure exceeds the rated value, the free end of the elastic element displacement, directly or after comparison, pushes the switch element to change the on/off state of the switch element, achieving the purpose of controlling the measured pressure. The elastic components used in pressure switches include single coil spring tubes, diaphragms, bellows, and corrugated tubes.
