DP305: Dummy Probe with 5 Outputs.
DP307: Dummy Probe with 7 Outputs.
The DP300 Series is an accurate and reliable electronic dummy probe for 2-wire optic and thermistor overfill protection systems.
Dummy probes are used when a tanker has fewer compartments than the number of channels on the gantry overfill monitor. The DP30x provides a simulation signal to unused channels in order to obtain a permissive signal from the gantry monitor.
The DP300 Series can simulate up to 7 compartments and is available in both 5 channel and 7 channel models.
Note: Australia uses DP305 only.
