The pressure switch H100-612 is designed for power plant steam turbines, and its working principle is based on pressure sensing and signal conversion. When the pressure in the system is higher or lower than the rated safety pressure, the disc in the sensor moves instantly, and the switch connector is pushed on or off through the connecting guide rod; when the pressure drops to or rises to the rated recovery value, the disc resets instantly and the switch automatically resets. This precise pressure sensing and fast response mechanism ensures that the steam turbine can maintain stable operation under various working conditions.

I. Performance advantages

1. Sturdy and durable: The cast aluminum shell is treated with epoxy resin powder coating, which can not only effectively resist the erosion of the external environment, but also has good impact resistance and vibration resistance, and can adapt to the complex and harsh working environment of the power plant.

2. High precision: It has extremely precise pressure set point adjustment function with an adjustment range of 125 to 3000psi (8.6 to 206.8bar), which can meet the high-precision requirements of power plant steam turbines for pressure control and ensure that the equipment operates in the best state.

3. Safe and reliable: It is equipped with an internal set point locking device to effectively prevent misoperation and ensure the safe operation of the steam turbine. At the same time, it has passed relevant certifications and meets strict safety standards.

4. Convenient wiring: The unique one-piece housing design is equipped with a tilted cover, which greatly facilitates wiring operations, reduces the difficulty of installation and maintenance, and improves work efficiency.

II. Technical parameters

1. Electrical connection: 1/2” NPT (internal thread), and two 7/8” diameter knockout holes are provided to facilitate the access and layout of electrical lines.

2. Pressure connection: 303 stainless steel piston and nitrile rubber O-ring, with 303 stainless steel 1/4” NPT (internal thread) pressure connection, ensure the stability and sealing of pressure transmission.

3. Switch output: Single-pole double-throw (SPDT) output, can be flexibly set to normally open or normally closed state according to actual needs to meet the requirements of different control logic.

4. Pressure resistance: The pressure resistance can reach 10,000psi (689.5bar), which can withstand the high pressure shock during the operation of the steam turbine and ensure long-term stable operation.

III. Application scenarios in power plant steam turbines

1. Pressure monitoring and control: Real-time monitoring of steam turbine steam pressure. When the pressure exceeds the set range, timely signal is issued to control the action of related equipment to ensure stable steam pressure and normal operation of the steam turbine.

2. Safety protection: As an important safety protection device for steam turbines, it quickly cuts off the power supply or starts the backup equipment when the pressure is abnormal to prevent equipment damage and safety accidents caused by excessive or low pressure.

3. Equipment linkage control: Linkage control with other equipment of the steam turbine, such as oil pumps, compressors, etc., automatically adjusts the operating status of the equipment according to pressure changes, and realizes the automatic operation of the entire system.

Pressure switch H100-612 has become a reliable guardian to ensure the safe, stable and efficient operation of power plant steam turbines by virtue of its excellent working principle, outstanding performance advantages, precise technical parameters and wide application in power plant steam turbines. Choosing pressure switch H100-612 is to provide strong guarantee for the stable operation and safe production of power plants.
