QDL80A 2088 Pressure Transmitter
On-site Digital Pressure Display Measurement and local display are integrated in one unit. Technicians can read pressure directly during inspection QDL80A combines pressure measurement with an on-site digital display. Technicians can read the current pressure directly at the process point during commissioning, inspection or troubleshooting without first opening the PLC program or checking a remote screen. The local display provides immediate confirmation that the transmitter is powered and responding to the process. This shortens routine inspection time, helps compare local and remote readings and makes initial setup more convenient when the pressure point is located away from the control room. |  |
Industrial Process Pressure Monitoring For continuous pressure measurement of stainless-steel compatible media. Suitable for pipelines, equipment and process systems QDL80A is intended for continuous process-pressure monitoring of media compatible with its stainless-steel wetted parts. Installed on pipelines, tanks or equipment, it converts pressure changes into a signal that can be used for indication, recording or control. Continuous electronic monitoring gives operators more information than occasional manual gauge checks and supports trend analysis over the full operating cycle. This makes the transmitter suitable for industrial process systems that require both local visibility and ongoing pressure data for automation. |  |
Analog Output + RS485 Option Supports 4–20mA output and optional RS485 MODBUS. Connect to traditional instruments or digital monitoring platforms QDL80A supports 4–20mA analog output and optional RS485 MODBUS communication. The analog version can connect to traditional PLC inputs, display meters or recorders, while RS485 allows digital pressure data to be integrated into modern monitoring networks. Providing both output approaches lets engineers match the transmitter to existing equipment or new digital systems without changing the basic pressure-sensing platform. This flexibility supports phased upgrades, remote data collection and more convenient connection to different control architectures. |  |
