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.
