About the APTSA Precision absolute and gauge pressure transmitter
Series APTSA transmitters are based on silicon piezoresistive sensing element in wheatstone bridge configuration. Thanks
to highly stable electronic components, these transmitters can be used in applications requiring long-distance signal transmission or in smart control systems.
APTSA pressure transmitters were developed mainly for pressure measurement in industrial refrigeration and air conditioning, compressor and pumps. They are also used for monitoring and control on automatic machines and general purpose industrial applications.
