Off-Equipment Mounting Kit
This kit allows off-equipment mounting of the ESPM, ES2PM and
ESDPM pressure senders. Recommended for protection from damaging
vibration. Customer supplies hose and fittings. Specify part number
30-00-0213 when ordering.
Wire/Connector Assembly
Listed below are replacement part numbers for all wire/connector
assemblies. Voltage converter included for 24 and 32 volt. Specify part
number when ordering.
1)
Thru 100 psi (689 kPa) [6.89 bar].
2)
Ranges above 100 psi (689 kPa) [6.89 bar].
3)
Mounting off-equipment recommended.
4)
Straight threads, for use with adapter nut.
5)
Separate adapter nut not required.
NOTE:
Boot is optional on ES2T
and ESDT temperature senders.
Specify p/n 00-00-3624.
Fuel level senders are for fuel tanks only.
Tank depths 6-24 in. (152-610 mm).
*
Available only as EG21PV-80-12 or -24-A. This model is designed to read senders with
resistance curve of 9.5 to 182 ohms, which are commonly supplied as standard senders.
**
Available only as EG21TV-300-12 or -24-A. This model is designed to read senders with
resistance curve of 240 to 18 ohms, which are commonly supplied as standard senders.
LOW VOLUME CONFIGURATIONS NOTE:
Low volume configurations may require minimum purchase quantities.

CAUTION: Certain danger to human safety and to equipment may occur if some
equipment is stopped without pre-warning. It is recommended that monitored
functions be limited to alarm-only or alarm before shutdown.
IMPORTANT:
EG21 Series gage and EGS21 Series Swichgage Movement and Illumination require 12 VDC to function.
For 24 volts systems, voltage converters are built into the electrical wire / connector assembly and supplied with the instrument.
Specify voltage when ordering. No designator is required for standard configurations.
