Introduction
Scope of Manual
This instruction manual provides installation, operat-
ing, maintenance, and parts information for the 4150K
and 4160K Series Wizard
R
II pressure controllers
and transmitters shown in figure 1. Refer to separate
instruction manuals for information regarding the con-
trol valve, actuator, and accessories.
Only personnel qualified through training or experience

Description
The 4150K and 4160K Series pneumatic pressure
controllers and transmitters use a bellows or Bourdon
tube sensing element to sense the gauge pressure,
vacuum, compound pressure, or differential pressure
of a liquid or gas. The controller or transmitter output
is a pneumatic pressure signal that can be used to
operate a final control element, indicating device, or
recording device.
Specifications
Specifications for the 4150K and 4160K Series con-
trollers and transmitters are listed in table 1. Table 2
explains available configurations and options.
Installation
Standard Installation
The instruments are normally mounted vertical with
the case/cover as shown in figure 1. If installing the
instrument in any other position, be sure that the vent
opening shown in figure 3 is facing downward.
Panel Mounting
Refer to figure 3.
Cut a hole in the panel surface according to the di-
mensions shown in figure 3. Remove the cap screws
(key 252), brackets (key 251), and vent assembly (key
15). Slide the controller or transmitter into the cutout
and reattach the brackets. Tighten the cap screw lo-
cated in the center of each bracket to draw the case
snugly and evenly against the panel. Reinstall the vent
unless a remote vent will be used.
