I. Overview
The AO910W immersion level transmitter utilizes a diffused silicon pressure-sensitive chip. It converts the liquid level signal of the measured liquid into a 4-20mA DC standard signal through a high-reliability amplification circuit. This product is available in two structures: integrated and split. The split products come in armored and corrosion-resistant versions. Both armored and corrosion-resistant models can withstand the侵蚀 of various corrosive liquids, meeting customer needs to the fullest extent. The AO910W immersion level transmitter is offered in two types: standard and intrinsic safety explosion-proof. The explosion-proof models are suitable for use in various harsh and dangerous environments.
