MODEL: HJPA–[1][2]–R[3]

ORDERING INFORMATION

• Code number: HJPA-[1][2]-R[3]

Specify a code from below for each of [1] through [3].

(e.g. HJPA-3A-R/Q)

• Frequency range (e.g. 0 – 152.3 Hz)

• Linearization data (max. 16 points)

Use Ordering Information Sheet (No. ESU-1673) to specify

linearization data when the I/O signals are non-linear.

• Specify the specification for option code /Q

(e.g. /C01/S01)

Note: Consult factory on applications with a sensor handling

periodically (& quickly) changing frequency (e.g. oval

flowmeter).
