Overview
2
BPT50-A is a combination of a pressure
sensor and a programmable loop-
powered 5-digit LCD display that allows
visualization of the measured pressure
from -9999 to 9999 units. BPT50-A is also
equipped with a programmable pressure
alarm driving a low-power electronic relay
output which can also be used to activate
various electric actuators for ON/OFF
pressure control.
Mounting and Wiring
Important note:
If the medium temperature
is higher than the maximum,
specified for your transmitter,
mount an additional
cooling spiral tube between
the object and the transmitter
in order to decrease
the medium temperature
at the transmitter input.
Mounting
Screw the BPT50-A transmitter to its
exact place using a preinstalled bush
with a female thread matching
the transmitter's one (¼", ½", etc.).
To ensure hermetical mounting,
use a proper gasket (e.g. DIN16258).
The right tightening torque depends
on the gasket material and shape
as well as on the mounting thread.
For mounting, use ONLY a proper
hexagonal wrench applying the torque
ONLY to the hexahedral transmitter head!
The installation site must be
protected from deep-freezing
and high-temperature sources, and
all environmental conditions must be
within those, specified for your
transmitter type (see '
Specifications
').
Wiring
Connect the transmitter via detachable
connector Mini-HIRSCHMAN by following
the markings as shown on the left.
Important note:
The supply voltage must be
greater than the required minimum
(marked on the label) plus
the load voltage drop at 20 mA!
