Section 3 Description
The HB Series Mini-Level Transmitter is an integral unit designed to measure static head pressure (level)
in Pasteurization Loop Balance Tanks and small Open Atmosphere Sanitary Storage Vessels. The unit
converts head pressure exerted by the product into a proportional 4-20 mA DC signal. This signal may
feed instrumentation such as controllers or digital indicators. The all stainless sealed design meets the
demands of damp or wet applications, and may be directly washed down during normal cleanup. Units are
typically shipped pre-calibrated from the Factory, with provisions provided for eld calibration via onboard
adjustment potentiometers (Pots).
Section 4 Wiring
A 12 to 40 VDC loop power source is required for operation of the HB transmitter. If below 24 VDC, it is
recommended that a regulated supply be utilized.
HB mini level transmitters are provided with either the standard M12 5 pin quick disconnect receptacle or
with a ½” NPT conduit connector option that includes a sealed four conductor, foil shielded sealed cable
connection.
Anderson recommends Molded cord-set P/N 42117H0025, 0050, 0100 for lengths 25ft, 50ft or 100ft. This
is a premium molded cord-set designed to meet both the electrical and environmental requirements of the
HB. Commercially available cord-sets may be used as long as shielding is connected to the attachment
nut.
For HB ordered with the conduit connection option conduit must be installed to meet environmental
protection rating. Conductor assignments as follows:.
RED = Loop (+) connection
BLACK = Loop (-) connection
GREEN = Not Used
WHITE = Not Used
GROUND = Attached at sensor
NOTE: If it becomes necessary to splice cable connections, be sure all joints are properly soldered
and sealed from moisture. As copper easily becomes contaminated from typical cleaning
solutions, poor quality connections will eventually affect 4-20 mA signal output of the
transmitter.

Section 5 Transmitter Electronic Zero Calibration
Upon installation, and at typical six month intervals, a Zero calibration adjustment must be performed. The
required procedure is as follows:
Tools required: Digital Multimeter (Known accurate)
Fine - straight bladed screwdriver
NOTE: Must be performed with the sensor installed in the vessel, with appropriate loop power
applied.
Be sure vessel is drained to a level at or below the sensor. The transmitter should be wired to the receiver
at this point. To prevent possibly shorting receiver inputs, it is recommended that loop power be shut
off while making test equipment connections. At the receiver, remove the (-) BLACK transmitter lead.
Connect the (+) RED meter lead to the transmitter lead just removed. Connect the (-) BLACK meter lead
to the resulting empty terminal in the receiver. The digital multimeter should be set in the mA DC mode.
At this point, apply loop power again taking note of the resulting meter reading. You should see 4.00
mA registering on the meter display. If not, remove the screw at the end of the sensor labeled “ZERO”.
Using the ne screwdriver, adjust the internal potentiometer until a reading of 4.00 mA is achieved. Once
complete, replace the protective screw over the Zero potentiometer. Remove test equipment and install
transmitter (-) BLACK lead back to receiver. Again, it is recommended that loop power be shut off while
disconnecting equipment to prevent shorting of the receiver inputs.

Section 6 Calibration Ranges and Adjustments
The HB series transmitter is typically supplied pre-calibrated from the factory. Calibration data is located on the
information stamping on the side housing:
CAL. RANGE: XXXXXXXXX (Factory Calibrated Range In Inches Of Water Column)
Calibration checks may be performed in the eld using known accurate pressure test equipment. Typical
devices read out directly in Inches of Water Column where 27.7” Water Column equals 1 psig. As the required
calibration pressures are very low, it is recommended that a test gauge having a direct Inches Water Column
scale be used. This will give the greatest resolution. In some instances, it may be required to alter calibration,
or perform calibration of the transmitter in the eld. Keep in mind that two ranges exist. A transmitter
supplied in the lower range cannot be re-spanned to operate in the higher range, and vice versa. Calibration
adjustments within the same base range are allowed. The procedure for adjustment is as follows:
Calibration Using Pressure Simulator
· Be sure sensor is properly wired to loop power - remove Zero and Span protective cap screws
· Attach multimeter as in Figure 3 (Readout in mA DC)
· Attach pressure calibration equipment
· Orient sensor as close as possible to position as if it were installed in vessel
· Perform ZERO potentiometer adjustment with NO pressure on transmitter (Meter to read 4.00 mA)
· Apply test pressure to transmitter
· Perform SPAN potentiometer adjustment on transmitter (Meter to read 20.00 mA)
· Replace sensor into vessel
· Perform ZERO potentiometer adjustment with NO pressure on transmitter (Meter to read 4.00 mA)
· Zero and Span are non-interactive - calibration is complete - replace protective cap screws
Calibration Using Product in Vessel
· Be sure sensor is properly wired to loop power - remove Zero and Span protective cap screws
· Attach multimeter as in Figure 3 (Readout in mA DC)
· Perform ZERO potentiometer adjustment with NO product on transmitter (Meter to read 4.00 mA)
· Fill tank to capacity with PRODUCT
· Perform SPAN potentiometer adjustment on transmitter (Meter to read 20.00 mA)
· Zero and Span are non-interactive - calibration is complete - replace protective cap screws
Calibration Using Water in Vessel
Specic Gravity = (Pounds Per Gallon for Product / 8.345)
· Calibration with water in a vessel that will hold another product requires Specic Gravity correction
· Determine Specic Gravity, or calculate if Pounds Per Gallon provided
· Correct for Specic Gravity: [ (16.00 mA / Specic Gravity) + 4.00 mA ] = Expected mA Signal
· Be sure sensor is properly wired to loop power - remove Zero and Span protective cap screws
· Attach multimeter as in Figure 3 (Readout in mA DC)
· Perform ZERO potentiometer adjustment with NO product on transmitter (Meter to read 4.00 mA)
· Fill tank to capacity with WATER
· Perform SPAN potentiometer adjustment on transmitter (Meter to read result of calculation performed above)
· Zero and Span are non-interactive - calibration is complete - replace protective cap screws
