HHGP is a kind of Huahai transmitter. In power generation, gas, nuclear power, oil refining, petrochemical and pharmaceutical plants, a large number of sensors are used to measure many physical quantities such as pressure, temperature and flow rate and to automate the production process. These sensors must be calibrated regularly to ensure product quality. But the characteristic of this kind of factory is that many pressure and differential pressure transmitters are used in the field, and the transmitter is often HHGP is a kind of Huahai transmitter. In power generation, gas, nuclear power, oil refining, petrochemical and pharmaceutical plants, a large number of sensors are used to measure many physical quantities such as pressure, temperature and flow rate and to automate the production process. These sensors must be calibrated regularly to ensure product quality. But the characteristic of this type of factory is that many pressure and differential pressure transmitters are used in the field, and the transmitters often need to be calibrated on-site. These calibration work occupies most of the working time of plant equipment maintenance engineers and technicians. In order to improve work efficiency and increase the normal working time of equipment, it is very important to reduce the time during equipment maintenance. MT is a high-precision digital pressure gauge for measuring pressure/differential pressure transmitters. It is designed to be an instrument that can improve the efficiency of on-site calibration. In calibration, first input the same pressure to the calibrator and the transmitter, and then compare the output of the transmitter with the measured value of the calibrator. HHGP is equipped with all the functions required for on-site calibration work. These practical functions include measuring the output of the transmitter (1-5 V or 4-20mA), providing 24 V DC power output for the transmitter, and displaying the output error of the transmitter as a percentage, and storing measurement data , Using Ni-Cd battery power supply. D/A conversion output can easily output data to recorders or other instruments. Of course, data can also be output via GP-IB and RS232 interfaces. Data can be output even when using 12 V DC voltage or Ni-Cd battery power supply. HHGP and standard pressure source MC100 are used in combination to form a calibration system. This system is very convenient for calibrating transmitters, pressure sensors and pressure gauges. Only use HHGP and standard pressure source or a hand pump to form a calibration system. Computers and other related equipment can also be used to automate the calibration system. HHGP can be applied to national standards agencies; nuclear energy-related institutions; national and social research institutions; power plants; automobile manufacturers and their affiliated companies; household appliances manufacturers; precision instrument manufacturers; semiconductor and electronic components manufacturers ;Pharmaceutical plant; heavy machinery manufacturing plant; oil refinery; chemical/petrochemical plant; engine manufacturing plant, etc. HHGP is a good choice for manufacturers.
