Thermal Mass Diff. Pressure Signal Processor

Thermal Mass Diff. Pressure Signal Processor – Overview

This high-accuracy thermal-mass differential-pressure sensor includes K-factor correction. The real-time display and versatile outputs make this the ideal tool. It is compatible with multiple throttling devices such as Pitot Tubes, Averaging Flow Tubes, Annubar Tubes, Venturi Tubes, Orifice Plates and V-Cones. It is a hot-wire sensor with a turndown ratio of 100:1 . Its Outputs include 4 … 20 mA, 0 … 10 V, Relay, and RS-485. It is accurate at 60 m/s: ±(1.5% F.S.) and has an IP rating of IP65.
