DJM model and DJY model Water Level electrode
The measuring device can be used to detect the level of
boiler drum, high and low pressure heaters, deaerator steam
machines and other heat exchangers. Regulators may also be used for
water tanks, condensers, water tanks and other liquid level
measurement
Second, the structural characteristics of
Electrode point level gauge in the power, petroleum, chemical and
other industries have a wide range of application history, however,
has not changed in the past as a idealized design, structure it in
a measuring device, the interface circuit design parameters were
secondary instrument there are some flaws, resulting in false
detection level phenomenon, especially in the spring and summer of
high and low pressure heater, deaerator exchange system level
detection, measurement error phenomenon higher frequency. This
creates a serious impact on production equipment operation safety
and economy. DJM series of electrical contacts water level gauge
type electrode and UDZ color digital intelligent electrical contact
level gauge support, widely used in electricity generation and
medium-sized boilers, dyeing, chemical and other industrial and
mining enterprises, the monitoring of boiler drum water level,
high-pressure heaters, except oxygen, evaporator, condenser, boiler
starting splitters and dual water-cooled generator water tank level
measurement and other conductive liquid level measurement.
