SMP858-TST 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.
