PTR-7/8 is an indicating type relative pressure switch made up of an analog electronic pressure gauge and a solid state pressure switch. It measures and displays the absolute pressure and the relative pressure between two different pressure sources. It is commonly used for pressure ranging up to 798 bar and has a wide range of applications in many industrial and process control automation fields.

The basic principle behind the working of PTR-7/8 is that it reads and reacts to the pressure difference between two ports. The pressure at one port is transformed into an electrical signal which is then compared to a preset pressure threshold. When the preset pressure is exceeded, the device activates its built-in relay to carry out the necessary action.

The PTR-7/8 is a versatile indicator and can be used to measure and switch pressure in a variety of applications. It is suitable for applications such as oil & gas, power systems, water & waste water, chemical & pharmaceutical industries, and alternative energy. It can also be used to measure and switch pressure processes in hydraulic, pneumatic, and HVAC systems.

In power systems, the PTR-7/8 can be used to monitor the pressure of boiler systems and coolant systems. It can detect changes in pressure levels and set alarms when an excessive pressure is detected. It can also be used in nuclear power plants to control the steam generator turbine pressure.

PTR-7/8 can be used in water and wastewater systems to monitor pump pressure and ensure optimal performance. It can also be used to detect and report leaks. This makes it an important component in chemical and pharmaceutical plants. In these industries, the PTR-7/8 can be used to monitor and control the pressure of liquid materials to ensure safe operations.

It can also be used in HVAC systems to control the pressure at different levels of the system. This helps maintain the correct pressure when air is cooled or heated. The PTR-7/8 is also used in vacuum applications where leaks in the system must be detected and reported.

The PTR-7/8 is a versatile and reliable pressure switch that is used across a wide range of industries. It is highly reliable and easy to maintain, making it a favorite among engineers and technicians. It is a low-cost option that is rugged and reliable. This makes it a popular choice in applications where cost and accuracy are primary factors.
