QDW90A-HF Anti-corrosion Pressure Transmitter
PTFE Anti-corrosion Structure for Aggressive MediaQDW90A-HF is a pressure transmitter designed around “PTFE Anti-corrosion Structure for Aggressive Media.” Uses corrosion-resistant wetted materials for chemical liquids and aggressive process media. The wetted structure is selected for aggressive media so the measuring point is less exposed to corrosion, residue and premature material damage. The feature is directly relevant to acid / alkali tank, chemical dosing and industrial process projects. Maintain reliable measurement in acid / alkali tank and corrosive media, helping engineers keep the installation, inspection and signal path easier to manage during long-term operation. | |
Pressure Monitoring for Corrosive LiquidsQDW90A-HF is a pressure transmitter designed around “Pressure Monitoring for Corrosive Liquids.” Measures pressure in acid, alkali and chemical liquids with a corrosion-resistant wetted structure. The wetted structure is selected for aggressive media so the measuring point is less exposed to corrosion, residue and premature material damage. The feature is directly relevant to acid / alkali tank, chemical dosing and industrial process projects. Maintain reliable measurement in acid / alkali tank and corrosive media, helping engineers keep the installation, inspection and signal path easier to manage during long-term operation. | |
Corrosion-resistant Pressure Signal OutputQDW90A-HF is a pressure transmitter designed around “Corrosion-resistant Pressure Signal Output.” Transfers the measured pressure signal to displays, PLCs or control systems from corrosive process points. The wetted structure is selected for aggressive media so the measuring point is less exposed to corrosion, residue and premature material damage. The confirmed values highlighted here are DC. The feature is directly relevant to acid / alkali tank, chemical dosing and industrial process projects. Keep corrosive pressure points connected to the control system, helping engineers keep the installation, inspection and signal path easier to manage during long-term operation. | |
