Based on metal capacitive technology & diffusion silicon,
YK1000 series pressure transmitters is designed by using imported
key raw material & parts,
and its performances & outward appearance achieve international
advanced level.
YK1000 series metal capacitive pressure transmitter is widely used
in technical areas such as petroleum
industry, chemical industry, steel and iron industry, electric
power, food, papermaking industry, spinning and weaving, medicine
and environmental protection and so on.
