additional engine rpm input (0 to 5 volt), suitable to be connected to ECU output or inductive clamp adaptor.
What is new in V3?
Enhanced engine RPM input circuit. Hi sensibility for traditional ignition and new ignitions (on-spark coils). Noise protection.
2 General purpose analog inputs 0-5v, suitable for lambda probe
Easy to use
SP-1 data acquisition unit (V4) with 8 input channels:
Engine rpm input
2 thermocouple type K input (up to 1000°C)
4 general analog inputs
2 counter inputs (available under request)
2 servo outputs (available under request)
Hall Effect Digital Sensor for measuring roller speed
Capacitive pickup to measure engine rpm
Installation cables and SportDyno software
Connection is done by using PC serial port, this makes very easy to connect this unit to any computer.
NOTE: Most laptopts do not have a serial port, but a FTDI serial-USB adaptor is provided to connect SP1 on this PCs. This adaptor creates a virtual COM port that can be selected on the program to work with the unit as usual. Theorically any RS232-USB adaptor will work with this device, requeriments are 115,200 baud transfer. We can supply a well-tested adaptor if you can not find a suitable one.
The equipment is completed with a modern Software for Windows, very powerful and easy to use. It allows to work simultaneously with several tests.
Power supply: 220V 50Hz/60Hz (Europe) or 115 volt 50Hz/60Hz (USA) (please specify when doing your order)
Data transfer: 115200 baud RS232C (DB9 Conn) (There is available a RS232-USB adaptor)
Roller rpm input connector (CN2)
Type of sensor: Hall Effect active sensor (doesn’t need external magnets)
Type of input: logical Level (active at high level)
Maximum frequency: 15 KHz (6,000 rpm with 150 teeth)
Maximum cable length: 6m
Run/Stop input SWITCH
Engine rpm input: capacitive type (reads high voltage pulses on ignition cables)
Display: LCD 16×2 Characters.
Installation and Connections V4
Dynamometer Installation V4:
CN1-additional engine RPM input, 0 to 5 volt. Suitable for ECU output, or external adaptors.
CN2-Roller Speed Sensor (Hall Effect), and Switch input
CN3-Load Cell, not available at SP1
CN4-Digital Counters and Servo outputs, available in next version 4b
CN5-Analog connector, Analog channels 1 and 3 (J and L), from 0 to 5 volt, suitable for Wideband Oxigen Sensor
CN6-Analog connector, Analog channels 2 and 4 (K and M), from 0 to 5 volt, suitable for Wideband Oxigen Sensor
Dynamometer Installation V3:
CN1- general purpose input. (lambda probe)
At CN1 connector are available two analog channels (input from 0 to 5volt) that can be used to connect a lambda probe such as Bosch LSM11.
CN2- pickup connection. pick-up should be mount close the geared tooth. Maximum frequency of teeth should not be greather than 15 Khz, so the gear teeth will be max of 150 teeth (for 6,000 rpm of roller).
Start/Stop Button on CN2 to control the dynamometer operation.
