Pressure Sensor
HORN Pressure Transmitter TGL014xxx
The pressure transmitter TGL014xxx from HORN is designed for measuring the absolute and gauge pressure of various liquids including gas and vapors. In general, the pressure sensor from HORN measures the pressure occurring in the engine compartment against the atmosphere. The piston defects can be detected by the means of this pressure measurement; thus, it is an essential variable in the assessment of the smooth operation of your engine.

Speed Sensor
HORN Speed sensor FGL 01620
The speed sensor FGL 01620 from HORN can be used both at extremely low speed, and almost full stop can be detected, and it is also applicable for highspeed rotations up to 20kHz frequency. It is a preferred sensor for offshore and marine purposes because of its vigorous stainless-steel design.

Water in Oil Sensor
HORN Water in Oil (WiO) system
The Water in Oil system from HORN consists of a sensor FRG00032, a connection box GHG02088-5, a connection cable KSG03244-1, and three relay outputs. Additionally, to the basic standalone version, is the option to get an analogue output for water content and oil temperature, as well as an indicator box with analog indicator(s), operating devices, and an acoustic alarm.
