SMP858-NST Monosilicon pressure transmitter is a high performance pressure transmitter with international leading technology meticulously designed by LEEG instrument, using the world's most advanced sensor technology and patent encapsulation technology. 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. • Measuring range: 4kPa-1MPa • Output signal: 4-20mA, 4~20mA/HART, customer • Reference accuracy: ±0.2% URL, ±0.5% URL • Stability: ±0.1% URL/ 36 months • Media temperature: with silicon oil -40-120℃, with Neobee oil -10-180℃ • Protection class: IP67 • Diaphragm material: SUS316L, Hastelloy C • Stability: ±0.2% URL/5 years • Process connection: DN50PN10, DN80PN10, DN100PN10, Tri-Clamp 1-1/2", Tri-Clamp 2" • Approvals: CSA, CE, EX-proof certificate
