eliminated, probe is rated to 750psi.
Installing the probe for environmental applications
For the HX200HR/HX200HR-RS
Mount probe using a ½” (ID) mounting clamp (not provided) over probe and attached it to a
surface where measuring. Avoid installation in direct line with water injection.
For the mounting the HX200 series Electronics
Mount the electronics with two # 8 sheet metals screws
Mounting centers are 3.1” from each other.
Power 12 to 28Vdc, 24 Vdc (typical) 25mA max
HX200 Connections:
Connect red wire (+) to the positive excitation source and the black wire (-) to a negative
excitation. The output load if isolated from the excitation voltage can be in line with either the red
or black wire. If the load shares a common connection to the negative excitation voltage, the
HX200 (-) terminals must be connected to the (+) of the load device.
HX200-RS Connections:
Connect white wire (+) to the positive excitation source and the black wire (-) to a negative excitation.
If using the unit as a loop powered device, the output load if isolated from the excitation voltage can
be in line with either the white or black wire. If the load shares a common connection to the negative
excitation voltage, the unit (-) terminals must be connected to the (+) of the load device. RS232
connections: Receive is the gray conductor, transmit is the blue conductor, ground is the brown
conductor.
Verify that the received signal agrees with the display value.
Things to avoid: submersion in liquids, condensing conditions and dew points above 95C (live
steam)
Quick reminder: provide sufficient air flow to sensor (positioning of sensor is important because
response time can be affected.
