THEORY,STRUCTURE

Based on the ceramic capacitor technology,When the liquid material increase, the ceramic capacitance pressure increase,make the capacitance value increase,Capacitance value is proportional to the pressure value.

CHARACTERISTICS

Flange installation,strong overload ability,good stability,better than 0.1% per year full scale,strong anti-interference,very high accuracy and repeatability,can arrived 0.2、0.5classic,can adjust zero point、full scale in scene.Good corrosion resistance of ceramic measuring interface.

APPLICATIONS

Suitable for sticky and slurry medium,strong corrosion liquid,rich in particle kind medium,not easy to jam.

*Because this transmitter is static pressure liquid level guage, its essence is pressure transmitter,when mounted in the bottom of container,the tested pressure is proportional with liquid level height.The max scale of 0…200m take water as example to calculate:namely the max scale of transmitter is 0…20bar,1bar correspond ten meters water column,the tested water scale is 0…200m.But selection table still use baras unit,such as scale 0…200m,should fill in the second place of selection table“20”. Users can fill in the actual figure according to their requirements.

MATCHED ACCESSORY-DISPLAY UNIT K02

This display unit can matched use combine with LV70 series ceramic capacitor stastic transmitter,the effect is to display the pressure value,output switch value signal according to the set value(this function optional,please specify when ordering).
CHARACTERISTICS:
● Can display physical value -1.9.9.9–9.9.9.9
● Pressure drop less than 4.5V, 3mA
● Can choose switch value output with two ways(light couple output).Can set switch point as 1.
● Key program, can be set:zero point/full scale/decimal point/damping time/switch alarm /NO and NC output.
● Large LED display,solved the problem that LCD can’t see clear in dark ambient.
●Suitable for various two line transmitter,no need power source.
● Max distinguishability of mini processor can arrive 1/216
● Note:Add install the displayer will lengthen the transmitter 19mm
