Nitrous Express now offers a 0-5V pressure sensor with a working pressure window of 0-1600psi. This sensor works when using the Max 5 to monitor and datalog N2O pressure. This will also allow the Max 5 to control when the bottle heater turns on/off. You can set the on/off psi in the Max 5 to send an activation signal to your bottle heater at any pressure you command. When using this sensor the Max 5 can also keep the nitrous system from engaging if the bottle pressure is too high or too low (by user adjustable high/low limits). includes: 0-1600PSI sensor, 3 wire pigtail harness
