GLR-2

The GLR-2 range of instruments, manufactured by the London based firm GLR Instruments Ltd., is an industrial grade range of digital sensors used for control and measurement purposes. They are available in a range of pressure and temperature ranges, making them suitable for use in a variety of industrial applications.

The GLR-2 instruments are designed to be used with a variety of digital input signals, including RS-232, CAN Bus, I2C Bus, and Modbus communication protocols. The GLR-2 range also provides an analog input option, allowing the user to connect a traditional analog signal, for example from a thermocouple or strain gage, to the instrument.

The GLR-2 instruments are designed to be extremely accurate over a wide temperature range. The internal components of the instrument are designed to be calibrated to the International Temperature Scale of 1990 (ITS-90) using an external thermistor, allowing highly accurate measurements of temperature within the range of the instrument. The GLR-2 instruments are also designed with a range of error input protection to ensure consistent, reliable data over its lifetime.

The GLR-2 instruments can be used in a variety of applications, ranging from industrial process control and measurement to environmental monitoring. The instruments are used in industrial applications for process temperature monitoring, as well as in monitoring the water temperature of cooling systems. GLR-2 instruments are also used in environmental applications for measuring air temperature, water temperature, and soil temperature.

The working principle behind the GLR-2 instruments is simple and straight forward. The instruments are designed to read electrical signals from transducers which can detect changes in pressure or temperature. These signals are then converted into an electrical current which the instrument can then process and display. The GLR-2 instruments also incorporate a variety of signal conditioners to ensure the data is accurate and reliable.

The GLR-2 is an essential tool for many industrial, environmental, and process control applications. With their wide range of temperature and pressure measurements, coupled with their robust design, these instruments are sure to provide reliable and accurate data for years to come.
