Tel-Tru P611 Specifications

TEL-TRU MANUFACTURING COMPANY

MODEL P611

PRESSURE TRANSMITTER

Industrial Silicon Glass Fused Sensor Series

KEY BENEFITS

Unique glass fused strain gauge sensor

●

provides exceptional calibration stability

●

Calibration certificate (NIST traceable) with
each transmitter

●

Re-rangeable in the field — minimizes
customer stocking

●

Static Accuracy +/-0.50%, +/-0.25%, or +/-

0.15% of calibrated span (combined effects
of linearity, hysteresis, repeatability)

●

All 316L stainless steel welded
construction for long service life in
demanding applications

APPLICATIONS:

● Hydraulic and pneumatic controls

● Hydrogen fuel cells

● HVAC compressor systems

●

Pump monitoring

● Die cast machines

● Plastic injection moulding

● Test stands

● Presses

● Oil and gas monitoring

● Laboratory testing

RANGES:

Many ranges from Vacuum to 0-10,000psi; also
metric standard Bar and Kg/cm2 ranges.
Custom ranges readily accomodated.

CONNECTIONS:

Many pressure and electrical connections
available. Custom connections can be
accomodated.

Stepped design of the
pressure chamber
minimizes any
effect on the
sensor caused
by overtight­ening during
installation

Robust, single
piece, 316L
sensor
construction without
O-rings or seals
provides
optimum media
compatibility

SENSOR

Single piece

diaphragm and
