Georg Fischer 2450 Specifications

Signet 2450 Pressure Sensors

1/2 in. union mount

Blind transmitter or digital (S3L) sensor

Features

• Test certificate included

• 4 to 20 mA or digital (S3L) output

• ½ in. male union process connection

• One-piece injection molded PVDF body

• Flush ceramic diaphragm

• Easy installation

• Choice of three pressure ranges

• Pressure or level measurement

The 2450 Pressure Sensor has a one-piece injection
molded PVDF body and ceramic diaphragm for superior
compatibility in corrosive liquids. Three pressure
versions allow for optimal resolution matched to your
sensing needs. Solid state circuitry eliminates drift
(no internal potentiometers).

These sensors are available with a proprietary digital
(S3L) output, or field-scaleable 4 to 20 mA output.
Dual-threaded ends allow in-line installation with
conduit connection, or add the integral adapters to
create a compact assembly with a field mount version
of the Signet 8250 Level, 8450 Pressure Transmitter or
the 9900 Transmitter.

Applications

• Level or Depth Sensing

• HVAC

• Scrubber Systems

• Pump Protection

• Water Management

• Irrigation Systems

• Wastewater

• Chemical Processing

• Pressure Regulation/Monitoring
