the United StatesThe INGENINST IGNGD series micro differential pressure gauge/switch/transmitter is an upgraded replacement product for the IGNGS series products. It does not have the switch dead zone of IGNGS products, and its accuracy has been improved from 2.5% to 1% of full range, with better switch response speed.
IGNGD products adopt microelectromechanical and digital technologies, which can simultaneously have three functions: differential pressure gauge, differential pressure switch, and differential pressure transmitter. The overall design is exquisite, reliable and durable.The IGNGD series products have three touch buttons that can achieve zero calibration, unit switching, relay setting, response time setting, range/signal calibration, and other functions. They also have two sets of alarm switches and LED alarm indicator lights.

Product Features:

● Adopting microelectromechanical technology, it is durable and long-lasting
4-digit high brightness digital display, clear and easy to read
● With switch or buzzer, freely set low low, low high, high high, interval alarm, etc
Five units can be switched: Pa, kPa, in w. c., mm w. c., mbar
● It has functions such as zero point and range adjustment, and a response time of 0.5-30s can be adjusted
● Equipped with transmitter output function and can be upgraded to wireless data transmission type

Typical applications:

IGNGDThe product is widely used for measuring differential pressure in clean rooms; Measurement of furnace negative pressure; Measurement of inlet and outlet pressure of air supply and induced draft fans; Differential pressure measurement before and after high, medium, and low efficiency filters. It can also be used for industrial applications such as air to gas ratio control and automatic valve control during combustion processes, as well as for monitoring and alarming blood pressure and respiratory pressure in medical and healthcare equipment, and in laboratories and research institutions related to differential pressure.
