Type 68 P/I
Transmitter type 68
Type 68 converts pneumatic pressure into a 4-20 ma electrical signal for
uses with data loggers or PLC controls.
The unit is suitable for DIN rail or line mounting and requires only a non-
critical DC power supply.
Optional IP65 weatherproof versions are available.
Type 140
Electronic I/P Converter
For service in demanding process control applications, the Type 140
is used to convert a 4-20 mA control current to a 3-15 psi pneumatic
signal for operating a control valve actuator.
The internal closed-loop control electronics assure high resolution and
long-term accuracy.
Fully encapsulated circuit boards provide added environmental
protection.
Type 140 is available in Intrinsically Safe and Explosion proof versions
with ATEX, CSA and FM approvals.
Type 422
Failfreeze Electronic
Converter
A major advance in I/P converter design, offering failfreeze in addition to
conventional I/P features
Advanced electronic control and a precision pressure transducer to
achieve outstanding performance
Intended for field application in which rugged construction, vibration
immunity, weatherproofing and reliability are essential, together with the
enhanced system safety gained from its failfreeze characteristic
Two wire operation from a 4-20mA control signal with output pressures
up to 120 psig (8 bar) as standard
