HALL EFFECT TRANSDUCERS

Product catalog summary

Description
The T and TM series Hall Effect Transducers are designed for use in heating, ventilation, air conditioning (HVAC), boiler systems, and various industrial applications. These transducers utilize a Hall sensor and a magnet to generate an electrical signal proportional to the applied pressure. The TM series includes a pressure gauge for pressure display without power.

Construction Features
The transducers feature a plastic casing made from Polyarylamide Solvay, with options for IEC 60695-2-12 GWFI approved materials. The sensitive component is made of AISI, and seals are available in EPDM, NBR, FPM, and silicone. The sensor is programmable, and the connector is a RAST 2.5 (AMP duoplug type). The protection degree is IP00, and the weight is 22 grams.

Operational Features
The operating range varies from 0 to 6 bar, with an overload pressure of ≤10 bar and a breakdown pressure of >20 bar. The fluid temperature can reach up to 110°C for short periods, and the ambient temperature can be up to 90°C. The transducers can handle liquids, gases, or water with typical heating circuit additives and glycols. The TM series includes a manometer displaying 0-3 bar.

Electrical Features
The supply voltage ranges from 5 Vdc (±3%) to 8-30 Vdc. Output signals are customizable for different pressure ranges, with electrical absorption of <9mA and a resistance load of ≥4.7 KΩ. Capacitance load is 10nF.

Approvals
The transducers comply with EN61000-4-2, EN61000-4-3, EN61000-4-4 standards and the 2002/95/EC European directive (RoHS).

Transducer Functional Curves
Functional curves are provided for pressure ranges of 0-3 bar, 0-4 bar, and 0-6 bar, with corresponding output signals. Detailed views of these curves are included for specific pressure ranges.

Electrical Connections and Dimensional Patterns
Details on electrical connections and dimensional patterns are provided, ensuring proper installation and integration into systems.

Catalog excerpts

HALL EFFECT TRANSDUCERS SERIES: T SERIES: TM DESCRIZIONE The T and TM series transducers find their optimal use in the following applications: • Heating system HAVC • Conditioning systems HAVC • Boiler systems (steam) • Industrial applications Consisting of a Hall sensor, the development of this transducer is based on the concept of the solicitation of a semiconductor by means of a magnet. The stainless steel sensitive element moves perpendicularly a magnet placed near the Hall sensor generating a potential difference on the opposite face of the semiconductor. By means of this effect an electrical signal is obtained which is proportional to the applied pressure. The TM series transductor is a variant of the T series with the addition of a pressure gauge that allows the display of the pressure even in the absence of power supply. It is made of reinforced technopolymer in such a way as to withstand mechanical stresses and high thermodynamic conditions. The use of ultrasonic welding technology makes the coupling of the components making up the product homogeneous and stable over time, avoiding metal joints or rivets.
