Capacitance Differential Pressure Transmitter
Pressure or differential pressure will cause changing of capacitance value, analog signal convert to digital signal via AD and then being transfered to microprocessor, processed by microprocessor thenconvertted to 4～20mA analog electricity signal via DA
Super performance, use to measure pressure, differential pressure,liquid level, rate of flow.
Standard 4～20mA,RS-485 communication interface
Support upgrade of basic scene control technique
Compatible with 316LSS,noncorrosive liquids.
Shipping and aviation industry.
Hydraulic pressure and pneumatic control system
Apply in Petroleum industry, chemical industry, electric power, metallurgy, hydrology etc process control.
Analog output: two –wire 4-20mADC
Digital output: two –wire 4-20mADC and superimposing variable digital signal accord with HART
supply voltage 12.5-45VDC
Max load resistor Rmax in loop decided by the supply voltage, see the below drawing. HART PROTOCOL require the load resistor not less than 250Ω,not more than 600Ω
Max. 1.5Km, multi-address communication can connect 15 smart transmitters Max.
4 digital display,5 digit LCD display, pointer type.
ExiaIICT5;explosion suppression type
Can positive transfer or negative transfer, but can not overstep the utmost value
ambient temperature -40-85℃(When choose LCD : -20-70℃)
Static pressure and single side overpressure
3.45KPa(absolute pressure)～31.2MPa（gauge pressure）
less than 5 sec.
Less than 0.16cm3
If occur malfunction, automatism diagnose function will output 3.9 or 21.0mA
To avoid the data are modified random, can utilize software or protect switch lock the record data
