Tel-Tru P161 Specifications

P161 Ultra-High Pressure Transmitter

Precision Grade

Up to 100,000 psi High Pressure Measurement

Designed for measurement of high pressure

Tel-Tru's P161 is designed for the OEM or end user where ruggedness,
high performance, and reliability are required at a competitive price.
Key feature of the all welded sensing element design is its small size,
which greatly reduces the amount of force exerted by high pressure.
The P161 is a one piece precision machined sensing element. This
feature makes the P161 ideal for high-cyclical / high pressure applications.

Manufactured for extended life cycle

The P161 is built using advanced manufacturing
techniques, with automated weld procedures, extreme
environmental burn-in and thorough residual stress relieving
techniques. The P161 is modular and configurable to meet
customers' exact requirements.

Designed for High Cycles

Ruggedized NEMA 4X packaging

Every P161 is rated to NEMA 4X standards regardless of
pressure range or format. Pressure ranges are available from
0-15,000 psi through 0-100,000 psi.

Certification

Every P161 is shipped with a NIST traceable calibration certificate.
