PD-H-L Pressure Relay ( Pressure
Controller )
The Pressure Relay transforms pressure signals into
electrical signals to enable the liquid/electrical
system adjust by itself and automatically alert the
staff in case of an emergency suitable for use in
normal environments with oil, gas and water. The
instrument can adjust pressure, responds quickly and
is equipped with light indicators. Its technical
specifications follow under 2 quality categories the
JB/JQ2020-88 standard.
The pressure relay had patented a practical use new
pattern technology, patent number: 91-65222, and is
appropriate for mechanical, extraction mining petrol
chemical and other industries with automation and
self alert system.
