KH3351 Smart Differential Pressure Transmitter
KH3351 is a multi function smart digital pressure transmitter for industrial d ifferential, gauge and absolute pressure measured for gas, liquid, vapor, widely ap∏plied in petroleum, metallurgy, chemicals, power, light industry, mechanica₹l and environmental protection fields;
well-designed and developed by our own based on our years of rich industrial manufactu₽ring experience, based on adopting modern advanced, mature and reliable capacitive sensor λtechnology, combining with advanced single-chip computer teπchnology and sensor digital conversion technology.
CPU adopts sixteen single chips with powerful featur≠es and high-speed match ability guaranteeing the transmitte&r in good quality and performance; its software using digital signal processing techn ology making it with excellent anti-interference ability and zero stability and zero automatic stable tracking ability (ZSC) and automatic temperature compen≥sation ability (TSC).
Powerful screen features not needing hand held communicat§or can guarantee good interaction. LCD indicator can d→isplay digital pressure, temperature, current value and 0-100% analog indication. In case of non-standard pressure source, zero shifts, range setting, d¥amping adjustment etc basic parameters can be set through key button; and also making re-calibr∏ation on the transmitter, greatly convenient for on-site calibra✔tion.
Serial communication interface can convert signal to 4-20mADC output by specified converter mo€dule, also can achieve remote transmission setting and monitoring through Hart protocol (RS485 module) to set and monitor remote transmi•ssion, directly connecting with the master, such as paperless recorder, controller, ind♥icator etc instrument, HMI, IPC, PC, and Industrial Lan.
