4 Introduction
The Tan Delta range of Oil Quality Sensors allow real-time reporting of oil quality in virtually
any application. The sensor utilises sophisticated electronics to indicate the current condition
of oil, relative to an initial profiled condition of new oil.
Based on the sensor output, the oil drain-down intervals may be extended on large industrial
equipment where the cost of replacing and monitoring the oil is expensive. The sensor can
trigger an investigation into the quality of the oil, preventing the need for expensive routine
maintenance.
The Tan Delta Sensors can reduce the overall operating cost of machinery through the removal
of routine inspections, waste oil disposal and subsequent renewal.
The Tan Delta range of Oil Quality Sensors are designed to be easy to use in a variety of
configurations depending on the monitoring equipment to which you would like to interface.
They use a simple connection to connect to a power supply and output the oil condition and
temperature on individual 4-20mA current sink outputs. The connection is also provided with
additional wires if you would like to use an RS485, CANbus or Modbus interface to connect to
an external device or system.
4.1 Important Safety Notes
Please pay attention to the following safety notes:
Standard Sensor is not IECEx certified.
Never reassemble, repair or tamper with a sensor.
Ensure that the supply voltage is within the specified range.
Ensure the load currents do not exceed the rated value.
Check all the wiring for correct connection before powering the unit.
Ensure the sensor case is earthed.
