OEM Differential pressure transmitter 401 0 ... 3 - 8 mbar

Product catalog summary

Overview: The Huba Control Type 401 pressure transmitters are designed for detecting ultra-fine changes in air pressure, particularly for optimizing combustion mixtures in gas boilers. They feature a unique dual-component diaphragm for high sensitivity and repeatability, even below 20 Pascal.

Specifications: The pressure range is 0 to 8 mbar, with a tolerance zero point of ±0.5% full scale (fs) and a full-scale tolerance of -1.5%/+0.5% fs. The resolution is 0.1% fs, and the total of linearity, hysteresis, and repeatability is ±0.3% fs. Long-term stability is ±1.0% fs according to DIN EN 60770.

Operating Conditions: Suitable for air and neutral gases, the medium/ambient temperature range is 0 to +70°C, with a storage temperature range of -40 to +70°C. The device can tolerate an overload of 25 mbar and a rupture pressure of 200 mbar.

Materials: The case is made of polycarbonate, the diaphragm of liquid silicon rubber, and the sensor of ceramic Al2O3.

Electrical Specifications: The output is 0.5 to 4.5 V, with a power supply range of 10.4 to 18 VDC. Current consumption is less than 8 mA at nominal pressure without load. The device includes polarity reversal protection and is designed for installation in equipment, with CE conformity being the customer's responsibility.

Mounting and Connections: The device features a 3-pole plug connector RAST 2.5 and can be mounted using snap mounting in sheet steel or mounting brackets. The recommended installation is with the diaphragm horizontal and pressure connections facing downward.

Compliance and Testing: The device complies with DVGW and the Gas Appliance Directive 2016/426/EG.

Accessories: Various accessories are available, including mounting brackets, connectors, and calibration certificates.

Contact Information: Huba Control AG has offices in Switzerland, Germany, France, the Netherlands, the UK, Singapore, and China, with contact details provided for each location.
