Differential Pressure Indicator Transmitter
Model No: KCDPIT Series (KCPTX-S)
Differential Pressure Indicator Transmitters are designed for accurate measurement, local indication and remote transmission of pressure difference across filters, flow elements, tanks and process equipment.
The transmitter measures the pressure difference between the high- and low-pressure sides and converts it into a proportional output signal. A 5-digit backlit LCD provides clear local indication, while 4–20 mA, HART and RS485 Modbus RTU options support remote monitoring and control.
Available with measuring ranges from 50 mmWC up to 25 bar and higher on request, multiple accuracy options, high static-pressure capability, and diaphragm materials including SS304, SS316, SS316L, Hastelloy C, Tantalum and PTFE-coated construction, the transmitter can be configured for a wide range of industrial DP applications. The product is available in standard configuration and with flange connection.
