Industrial Applications

1. Chemical Dosing Tank Vacuum and Pressure Control

Utilizing the pressure transmitter to monitor slight vacuum and low-pressure cycles in highly corrosive chemical dosing tanks. The high-alloy stainless steel construction in contact with the medium and CRC 4 rating (very high corrosion stress) ensure longevity when exposed to aggressive liquid or gaseous media.

Problem Solved

Eliminates frequent sensor failure caused by corrosive chemical exposure while accurately maintaining tank pressure between -1 and 1 bar, preventing tank deformation and ensuring consistent fluid dosing.

2. Pump Cavitation Prevention in Wastewater Treatment

Deployed at the suction inlet of industrial centrifugal pumps to precisely measure relative pressure from -1 bar up to 1 bar. The robust IP67 degree of protection and piezoresistive measurement method provide reliable continuous 4-20mA signals back to the PLC over long cable runs, immune to electrical noise.

Problem Solved

Prevents pump cavitation and expensive dry-running damage by instantly detecting destructive vacuum spikes in the suction line, ensuring reliable continuous operation in harsh, wet environments.

3. Low-Pressure Corrosive Gas Line Leak Detection

Monitoring pressure stability in low-pressure industrial gas supply manifolds. The sensor's 0.1 %FS repetition accuracy allows it to detect very minor pressure fluctuations, while the standard G1/4 pneumatic connection and M12x1 plug facilitate seamless integration into existing pipeline infrastructure.

Problem Solved

Rapidly identifies micro-leaks or flow interruptions in low-pressure gaseous media networks, allowing for predictive maintenance and averting hazardous gas accumulation or process shutdowns.
