high accuracy, high reliability, high stability, wide temperature range, temperature, static pressure effect is small
Silicon capacitive differential pressure sensitive chip is the sensitive element in HB3188 Series silicon capacitive differential pressure transducers,which is self-designed with MEMS techinique,The transducers have full solid state, high accuracy,high reliability,stability,wide temperature range,low static pressure effect,superior unilateral overload capacity.The transducers have the conforming advanced technology,superior anti-inerference in spot,two-way configuration,the HART communication protocol.Digital temperature compensated technique, stainless steel package,316L isolation diaphragm package and standard differential pressure connector are adopted. It is widely used in measuring differential pressure, flow of liquid and gas in petroleum, chemistry, electricity, light industry food, environment protection and boiler control.
