Vortex Probes VA40 ... ZG4

Vortex Probes VA40 ... ZG4 - variable insertion depth, various sensor materials, working temperature range up to +240 °C

Vortex probe VA40 with sensor head diagonal dimension 40 mm and connection housing.

Probe materials: stainless steel, Hastelloy, titanium.

Working temperature range up to +100, +180 or +240 °C.

Sensor length 250 ... 2000 mm in 250 mm stages. Process connection via probe guide piece SF with thread or flange. Optional with integrated temperature sensor Pt100.

Suitable for fixed measuring of actual flow velocity v [m/s], flow rate V/t [m³/h] and temperature t [°C] (optional) in clean as well as condensate and particle-laden gases.

Signal evaluation with integrated transducer UVA (optional output: temperature 4-20 mA), separate transducer UVA or system unit µP-Vortex (VT-VA with integrated Pt100).

For ATEX category 1/2G and category 1/2D (zone 0/1, zone 20/21) applications, an additional isolation / supply unit LDX is necessary.

Output signals:

- 4-20 mA (flow-proportional)

- quantity pulse / limit value

Configurable via RS232 interface and software UCOM (with integrated UVA).


Examples for common applications:

Sewage gas / biogas quantity measurement in wastewater treatment
