The TP-4 is a 3 1/8” sunlight readable 4-channel universal analog input color display instrument. Each channel can be individually programmed to display either pressure, temperature, current or volts from a universal analog input that can interface to many sensors such as oil temperature, coolant temperature, oil pressure, fuel pressure, manifold pressure, boost pressure and many more.
The TP-4 can display any combination of 1 to 4 analog channels in a horizontal / vertical bargraph or a numeric display format.
Pressure can be measured using standard automotive resistive senders (e.g. VDO 2, 5 and 10 Bar), Rotax 4-20mA senders as well as voltage output pressure senders (e.g. UMA). Temperature can be measured using standard automotive resistive senders (e.g. VDO, Westach) as well as the MGL Avionics precision LM335 semiconductor sensor. In addition the temperature, pressure and current inputs can be programmed to a user defined curve for custom senders.
All analog channels have a programmable low and high alarm. This results in a contact closure that is typically used to switch a warning lamp on. The TP-4 also records the minimum and maximum values reached for each channel in permanent memory.
The TP-4 can also be optionally interfaced via the CAN bus to an external RDAC unit (Remote Data Acquisition Computer). This allows for easier installation as the RDAC unit is normally mounted in the engine compartment.
