Moisture in Oil

The Vaisala HUMICAP

®

Hand-Held

Moisture for Oil Meter MM70 is

designed for field-checking MMT330

transmitters.

The display alarm allows any

measured parameter to be tracked,

with freely configurable low and high

limits.

Versatile Outputs and

Data Collection

The MMT330 can support up to three

analog outputs; an isolated galvanic

power supply and relay outputs are

also available.

For serial interface the USB

connection, RS232, and RS485 can be

used.

MMT330 is also capable of applying

the MODBUS communication protocol

and, together with an appropriate

connection option, provides either

MODBUS RTU (RS485) or MODBUS

TCP/IP (Ethernet) communication.

The data logger, with real-time clock

and battery backup, guarantees

reliable logging of measurement data

for over four years. The recorded

data can be viewed on the local

display or transferred to a PC with

Microsoft Windows

®

software. The

transmitter can also be connected to

a network with an optional (W)LAN

interface, which enables a (wireless)

Ethernet connection. A USB service

cable makes it easy to connect the

MMT330 to a PC via the service port.

Easy Installation

MMT330 transmitters have several

options for transmitter mounting.

They are delivered installation-ready,

pre-configured with all settings.

Water Content as ppm

Conversion

In addition to water activity, the

MMT330 can output ppm, the average

mass concentration of water in oil.

Vaisala has this conversion readily

available for mineral transformer oil.

For other oils, the oil-specific

conversion coefficients can be

programmed into the transmitter

if the water solubility of the oil is

known.

Graphical Display of

Measurement Data and

Trends for Convenient

Operation

The MMT330 features a large

numerical and graphical display with

a multilingual menu and keypad.

It allows users to easily monitor

operational data, measurement

trends, and access measurement

history for the past 12 months.

The optional data logger, with

real-time clock, makes it possible

to generate over four years of

measurement history and zoom in on

any desired time or time frame.
