Sensor Pods

Each Krill Sensor Pod is specialized for measuring a particular system on a boat. Additional Pods may be added at any time to expand the number of sensors that are desired to be monitored.

ESM1 Electrical System Monitor

ESM_POD The ESM1 is designed to measure all of the parameters of an electrical system found on most medium sized vessels. The ESM1 supports 3 basic types of input:

AC (voltage, current, power, frequency) - 2 inputs
Battery (voltage, current, capacity remaining) - 3 banks
DC (current) - 5 sources or loads
Tank Level senders with Voltage outputs

A typical application would be to connect the ESM1 to the following equipment:

AC shore power
AC generator
House battery bank
Two starting battery banks for each engine
Two alternator DC outputs from each engine
Two inverter chargers
Total DC current consumption

TSM1 Tank & Switch Monitor

Each TSM1 is designed to measure up to 5 tanks / temperature sensors and up to 5 switched circuits.

Any tank equipped with a resistive sender may be used. For increased accuracy, each sender is measured with a regulated voltage that is completely isolated from the state of the House battery. The TSM1 can also optionally utilize up to 8 custom calibration points that take the tank shape into consideration when determining fluid amount remaining.

Krill's thermistor based temperature sensors may also be connected to the tank ports.

A switched circuit is any type of electrical circuit that is switched on or off, such as pumps, fans, lights or contact switches. The TSM1 senses the presence of voltage for these inputs; any simple contact switch must be wired to an external voltage source to operate correctly.
