Page 7: General
Another application example using the CLM100 is shaft speed monitoring. A commercially available 4-20mA rotational rate sensors is coupled to the shaft of interest and the CLM100 converts the transducer to an RPM that can display. And if you’re concerned about the force ®... -
Page 8: Clm100 Accessories
CLM100 to monitor pressures of gasoline, you must obtain a pressure transducer that is approved for use with gasoline. For other parameters, Maretron does not offer any accessories for the CLM100; however, the CLM100 is compatible with any transducer which offers an industry standard 4-20mA current loop interface and is able to operate with a current loop excitation voltage of 12-15VDC. -
Page 9: Theory Of Operation
The CLM100 can measure parameters with a resolution of approximately 0.33% of full scale. In many cases, the resolution to which the CLM100 can measure a parameter may be lower than the resolution at which NMEA 2000 represents the parameter. As an example, if a... -
Page 10: Accuracy
NMEA 2000 data types used to transmit the parameter value. For example, if you connected a DC voltage sensor with a range of 0-20VDC to the CLM100, the CLM100 could measure the parameter transmitted by the CLM100 to a resolution of 0.067V;... -
Page 11: Installation
Please consider the following when choosing a mounting location. 1. The CLM100 is waterproof, so it can be mounted in a damp or dry location. 2. The orientation is not important, so the CLM100 can be mounted on a horizontal deck, vertical bulkhead, or upside down if desired. -

(or an NMEA 2000 compatible cable) by connecting the female end of the cable to the CLM100 (note the key on the male connector and keyway on the female connector). Be sure the cable is connected securely and that the collar on the cable connector is tightened firmly. Connect the other end of the cable ®... -
Page 13: Transducer Connections
Transducer 5 (negative terminal) Please refer to Figure 3 for connecting the CLM100 to a 4-20mA current loop transducer. This figure shows the connection of the 4-20mA transducer to channel 0 via the terminals named P0+ and P0-. Connections to other channels are similar. -

20mA. The CLM100 supplies a minimum of 12V to each transducer at the maximum loop current of 20mA. In order to ensure that your transducer will work with extended wires, you should calculate the voltage drop across the extension wires. -
Page 15: Configuring The Clm100
First, calculate the resistance of the wire . Remember that the wire length needs to WIRE WIRE be multiplied by two, because the current needs to travel from the CLM100 to the transducer and then back again. 16.14Ω �� = 2 × ��... -
