The Series HATX transmitter has been carefully calibrated before
shipment to you, and it should be handled with the same care given any
precision instrument. Pressure range and dimensions are reported on the
specifications bulletin for the transmitter.
Ambient Conditions
Do not use in ambient conditions corrosive to anodized aluminum, or
submerge in liquids, subject to spray or vibration environment.
Electrical Connections:
Electrical
The electrical circuit is equivalent to a 4-terminal network which can be
grounded at only one point, either at the negative excitation or the
negative signal output lead, but must not be commoned or grounded at
more than one point.
The unit must be operated with the case connected either to the
negative excitation terminal or to the negative output terminal. Failure to
do this may result in damage to, or unsatisfactory
operation of the unit. This connection may be made by connecting shield
and black (negative excitation) leads or alternatively by connecting the
shield and negative output signal leads together. Best shielding against
noise will be obtained by connecting the shield and negative excitation
leads. Circuit is reversed voltage protected for at least 5 minutes.
Internal transient suppression network is provided for short duration
transients to 150 volts.
In some instances, use of long cables (several hundred feet long), may
introduce enough cable capacitance into the output circuit to cause
output oscillation. If encountered, this oscillation may be eliminated by
connecting a 100 ohm resistor (1/8 watt or larger) in series in each of the
output leads at the end of the 2 ft transducer cable. These series
resistors of course add to the output resistance.
