Description:
Based on the Magnehelic® design, this gauge retains the low DP sensitivity and accuracy whilst adding two relay outputs for high and low DP alarms. The Photohelic® principle uses the standard gauge pointer to interrupt infra-red beams at the adjustable set points, which then drive the output relays. High and low set points are adjustable using the front mounted knobs.
Features:
• Magnehelic® design
• Retains low DP sensitivity and accuracy
