Pengukur tekanan diferensial kontak listrik

Prinsip

Electrical contact differential pressure meter adopts spring tube as pressure sensing element. The differential pressure calculation mechanism calculate the difference value of the two pressures, which is accurately indicated by the pointer on the dial. When the indicated value reaches the given upper limit and lower limit, the relay acts to close the external circuit for alarm or trigger other forms of automatic control.
