MODEL: JPA–[1][2]–[3][4]

ORDERING INFORMATION
• Code number: JPA-[1][2]-[3][4]
Specify a code from below for each of [1] through [4].
  (e.g. JPA-23-B/Q)
• Frequency range (e.g. 0 – 152.3 Hz)
• Special output ranges (For codes Z & 0)
• 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).
