Tank senders connect to display via a one wire bus which saves wiring costs
LPG tank connection compatible with existing electric senders
Calibrate LPG at first fill of tank or it can be factory calibrated
Multiple versions meet the needs of differing configurations:
709PH: Three holding tanks, LPG tank,water pump/heater switches
709: Three holding tanks, LPG tank
709-4: Four holding tanks
Accuracy: +/- 10% or better, limited by resolution and tank shape
Operating temperature range: +32 to +140 oF (0 to + 60oC)
Sender materials: 0.008” thick glass epoxy circuit board with conformal coating for circuit protection. Laminated on the back with 3M 300LSE Bonding Adhesive.
System power requirements: Display requires 12 volts from the RV battery, the system will function from 11 volts to 16 volts. Current drain is less than 200mA.
Wiring: Common two wire conductor (signal and ground) required from the display to each sender. 12 V power and ground required for display. Single wire required for LPG sender if sender grounded at tank.
LPG sender characteristics: Display will work with an LPG sender maximum resistance of 50 ohms to 500 ohms. Display shows increasing level as resistance increases. System must be calibrated with the LP tank full, or can be factory calibrated.
