SV-EMS-220/221 Installation and Configuration

7-40 SkyView System Installation Guide - Revision R

Use an Adel clamp similar to the

above to secure the pressure sensor

Oil Pressure Sensor

The oil pressure sensor may be connected to any general purpose input pin on the SV-EMS-

220/221’s D37, however, we recommend that it be connected to pin 6 on this connector.

The SV-EMS-220/221 supports several oil pressure sensor installations. The Dynon-supplied

sensor and the Rotax and Jabiru pre-installed sensors are the most common.

Kavlico Brand Dynon-Supplied Brand Oil Pressure Sensor (101693-000)

Mount the oil pressure sensor securely using an Adel clamp or other method such as using a

transducer mounting block on the firewall. Dynon does not recommend mounting the sensor

directly to the engine to minimize the chance of mechanical failure of the transducer due to

engine vibration. Unlike Dynon’s older oil pressure sensor, the Kavlico pressure sensor has a

dedicated ground wire, eliminating the need to use the sensor case as ground.

Connect the red wire to SV-EMS-220/221 D37 pin 18 (white/red). This connection may be

shared with other sensors, depending on your installation.

Connect the green wire to SV-EMS-220/221 D37 general purpose input of your choosing

(nominally pin 6)

Connect the black wire to Ground. Any the black ground

wires on the SV-EMS-220/221 D37 harness are suitable for

this purpose.

Legacy Dynon Oil Pressure Sensor (100411-002)

First, mount the oil pressure sensor to a fixed location using

an Adel clamp (see Figure 36) or other secure method. The

oil pressure sensor must not be installed directly to the

engine due to potential vibration problems. Dynon Avionics’

sensor is supplied with a 1/8” NPT pipe thread fitting. An

adapter might be necessary for some engines. Please see the manual supplied by the engine’s

manufacturer. You must use appropriate pipe fitting

adapters and ensure that the case of the sender has a

connection to ground. This is critical for functionality.

Crimp a standard #8 ring terminal onto general purpose

input wire chosen for oil pressure. Unscrew the stud cap

from the threaded stud. Place the ring terminal on the stud

and secure the cap down sandwiching the ring terminal.

Due to vibration issues, never connect the

sensor directly to the engine.
