Schedule
EQUIPMENT:
Equipment and systems covered by this certificate are as follows:
The HU-L24-IS-nnK-PSIS-Enn-Pnn-Knn-Bnn 4-20mA Pressure Transmitter consists of encapsulated electronics on two separate
printed circuit boards which connects to a silicon piezoresistive strain gage arranged in a Wheatstone bridge configuration mounted in
a two-part housing. The upper half of the housing has one of the two printed circuit boards, dedicated for EMI protection. The bottom
half of the two part housing is comprised of the second printed circuit board (main electronics) and the strain gage element which is
mounted on a thin walled section of the enclosure. The strain gage connects to the main board in the lower housing via a ribbon cable.
There is no direct process connection between the pressure sensor and the external environment being measured. External electrical
connections are made to the connector fitted at one end.
The equipment has the following safety description (Entity Parameters):
Ui = 28V, Ii = 110mA, Pi = 1W, Ci = 60.89nF, Li = 7.7mH
CONDITIONS OF CERTIFICATION: NO

DETAILS OF CERTIFICATE CHANGES (for issues 1 and above):
Issue 1 - Modification of the EMI board to add a common mode choke and protective circuitry to better protect the Hammer Union
sensor against surges and fast transients. The Li parameter has been modified as a result. Also Ui was lowered.
