3 Product Description
3.1 General
The MOP301 is a robust probe for moisture in oil and temperature measurement. Its IP66 rating and the
E+E proprietary sensor leads protection make it ideal for highest requirements. It features a moisture in
oil measuring range of 0...1 aw, a temperature measuring range of -40...120 °C
(-40...248 °F)
and a 20 bar
(290 psi)
pressure rating. Measurement is possible within oil pipes as well as in almost still oil.
The MOP301 is typically deployed in monitoring of lubrication, hydraulic and insulation oils as well as diesel
fuel in equipment and machinery. The oil to be monitored may be mineral, synthetic or biodegradable.
Installation is simplified by various mounting options which are supported by E+E accessories.
The MOP301 provides the measured data at its digital RS485 interface via Modbus RTU protocol. The
M12x1 connector links the probe to the digital infrastructure.
