The type 450 is the new relative and differential pressure transmitter from Huba Control for low pressure measurements, based on the cantilevered beam technology and built in a compact housing.

The type 450 is characterized by an excellent accuracy and long-term stability in highly demanding environments and is also available with analogue and digital signal outputs (I2C). The pressure range covers from -1.5 … 1.5 mbar and from 0 … 3 – 100 mbar and is temperature compensated from -10°C up to +80°C.

Technical data:

• Medium: Air and neutral gases
• Pressure range: -1.5 ... 1.5 mbar / 0 ... 3 – 100 mbar
• Output: 0.5 ... 4.5 V, digital I2C, ratiom. 10 ... 90%
• Electrical connection: PCB
• Pressure connection: Tube connector

The new Type 240 flow sensor is designed for precise and stable flow measurement even under difficult conditions, with enhanced resistance to high system pressures and media temperatures.

This vortex flow sensor is ideally suited for diverse applications across numerous indus-tries and markets. The sensor paddle itself is made of the high-performance material PPSU and is PFAS-free.
Type 240 complies with the safety standard UL 61010-1* and is approved for drinking water according to WRAS*, ACS*, and UBA* regulations.

Versatile Applications
The Type 240 is designed for liquid media with different specific viscosities, from refrigerants to drinking water. The proven Vortex principle ensures high measuring accuracy. Moreover, its compact design without moving parts makes the sensor extremely robust, low-maintenance, and durable. It can be mounted directly on the manifold and easily integrated into existing systems.

A particular highlight is its resistance to water hammer: The Type 240 can easily with-stand pressure peaks up to 100 bar (1450 psi).
