The pressure switch RC771BZ090H is used in power plants to monitor system pressure. Once there is a slight disturbance, the alarm will sound immediately. Today, let’s take a deep look at the technical parameters of RC771BZ090H, especially the pressure range, alarm threshold, and electrical characteristics, to see how it can be used in power plant applications.

The pressure range of RC771BZ090H is simply the pressure range it can monitor. For this product, the pressure range is from 0 to 90 bar, which is equivalent to 0 to 8820 kPa. In a power plant, this pressure range is not small, enough to cover various working conditions such as steam pipes, cooling systems, and lubricating oil systems. Whether it is the high-pressure steam in the boiler or the lubrication pressure of the generator bearing, RC771BZ090H can keep a close eye on it. Once the pressure exceeds the set range, it will immediately pop up a reminder.

The alarm threshold is the bottom line of RC771BZ090H. As long as the pressure touches this line, it will sound the alarm without hesitation. This threshold is adjustable, and technicians can set it manually according to the needs of different equipment in the power plant. For example, if the boiler steam pressure is set too high, the RC771BZ090H will wake up the operator in time like an alarm clock to prevent safety accidents caused by excessive pressure. On the contrary, if the pressure is too low, such as insufficient pressure in the lubricating oil system, it will also issue a warning to prevent equipment wear and tear and ensure the normal operation of power plant equipment.

Electrical characteristics, which are related to whether the RC771BZ090H can accurately transmit signals to the control system. The RC771BZ090H uses SPDT (single-pole double-throw) contacts, which can carry a maximum current of 10 amperes and a voltage range of 250 volts AC or 30 volts DC. This means that even in a high-current, high-voltage environment such as a power plant, the RC771BZ090H can be as stable as a mountain to ensure the accuracy and reliability of signal transmission. Moreover, its contact design has another advantage, which is that it can be flexibly connected to various types of control systems, whether it is PLC or relay, it can be easily connected, so that the signal transmission is unimpeded.

In the actual application of power plants, RC771BZ090H is like a tireless sentinel, always guarding the safety of key equipment. For example, on the steam pipeline, RC771BZ090H monitors the steam pressure. Once the pressure is abnormal, it immediately notifies the control system and takes emergency measures to prevent the pipeline from rupture or explosion. In the lubricating oil system, it is responsible for monitoring the lubricating oil pressure to ensure that the generator bearings are fully lubricated to avoid overheating or wear. In addition, RC771BZ090H can also be used to monitor the pressure of the cooling water system to prevent equipment overheating caused by poor cooling and ensure the stable operation of the entire power plant.

In the application of power plants, the pressure switch RC771BZ090H has become an indispensable guardian with its wide pressure range, adjustable alarm threshold and stable electrical characteristics. Whether it is high-pressure steam, lubricating oil pressure, or cooling water system, it can accurately monitor and issue timely warnings to ensure the safe and stable operation of power plant equipment.
