The high accuracy pressure transmitter MBS
4000 is designed for use in almost all industrial
applications, and oers a reliable pressure
measurement, even under harsh environmental
conditions.
The exible pressure transmitter programme
covers a 4 – 20 mA output signal, absolute or
gauge (relative) versions, measuring ranges
from 0 – 1.6 to 0 – 400 bar. A wide range of
pressure connections.
Excellent vibration stability, robust
construction, and a high degree of EMC / EMI
protection equip the pressure transmitter to
meet the most stringent industrial
requirements.
Features
• Designed for use in severe industrial
environments
• Enslosure and wetted parts of acid-resistant
stainless steel (AISI 316L)
• Pressure ranges in relative (gauge) or
absolute from 0 up to 400 bar
• Output signal: 4 – 20 mA
• A wide range of pressure connections
• Fully digitally compensated
• Accuracy 0.5% FS max.
• UL approved
