high temperature differential pressure measuring instrument transmitter with valve manifolds Introduction differential pressure measuring instrument transmitter is a measure of the difference between the two ends of the transmitter ,output standard signal (eg 4 ~ 20mA, 1-5V) differential...Send Inquiry
AT3051 series intelligent differential pressure transmitters adopt the capacitive sensor chip with the most mature technology, which is the most widely used by foreigners,bring in the advanced production process and technology, use modular design and all-patch-packaging components to make the differential pressure transmitter compact and perfect.
HB3351 series intelligent differential pressure transmitters have 3 models: normal analog model, conventional smart model and standard model. It can be read at night with LCD backlight. The smart series can be adjusted at site through the spot button. The maximum measuring range ratio is 50:1.
