LEEG SMP858-TST-H Monosilicon Absolute Pressure Transmitter

LEEG SMP858-TST-H Absolute Pressure Transmitter is a high performance pressure transmitter with international leading technology meticulously designed by LEEG.


LEEG SMP858-TST-H Absolute Pressure Transmitter is a high performance pressure transmitter with international leading technology meticulously designed by LEEG. The sensor locates on the top of the metal body and stay away from the medium interface to realizes mechanical isolation and thermal isolation.

Glass sintering sensor wire realizes high strength electrical insulation of metal base and improves the capability of flexibility of electronic circuit and transient voltage resistance protection. All these original encapsulation technologies enable SMP858-TST to easily cope with extreme chemical occasion and mechanical load, and own strong resistance to EMI, sufficient to respond to the most rigorous industrial environment applications.
