USER'S GUIDE____________________________________________________________________ The MMT318 and MMT317 powers up with 24 VDC. Output alternatives are analog outputs 0/4... 20mA and RS232C serial line. The transmitter measures and calculates the following quantities: Quantity Metric Unit Non Metric Unit aw water activity °C °F T Temperature ppm (for transformer oil only)
Take care not to damage the pipe of the probe. If the pipe is damaged, the probe head is less tight and will not go through the clasp nut. Make sure that the filter is tightly fastened to protect the sensors. VAISALA _______________________________________________________________________ 11...
USER'S GUIDE____________________________________________________________________ Mounting the transmitter/Removing the transmitter unit Mount the plate onto the wall by using four/two screws (∅4.5 mm/6.0 mm). Place the transmitter onto the mounting plate and fasten it by using two allen screws. The transmitter module can be unfastened for calibration by releasing two allen screws on the left side.
45±5 Nm (33±4 ft-lbs). Be careful not to over tighten' the nut. When the probe is used in a pressurized processes the sensor head should preferebly be installed through a ball valve assembly. VAISALA _______________________________________________________________________ 13...
Ball Valve Installation Kit for MMT318 The ball valve installation kit (Vaisala order code: BALLVALVE-1) is preferred when connecting the probe to a pressurized process or pipeline. Use the ball valve set or a 1/2" ball valve assembly with a ball hole of Ø14 mm or more.
Tighten the nut a further 50 -60º (ca. 1/6 turn) with a wrench. If you have suitable torque spanner, tighten the nut to max 45 ± 5 Nm (33 ± 4 ft-lbs). max . 60° 0511-109 Tightening the Clasp Nut The following numbers refer to above: Probe Clasp nut VAISALA _______________________________________________________________________ 15...

USER'S GUIDE____________________________________________________________________ The following numbers refer to above: Fitting body NOTE Take care not to over tighten the clasp nut to avoid difficulties when opening it. CAUTION Take care not to damage the probe body. A damaged body makes the probe head less tight and may prevent it from going through the clasp nut.
MMT317 with Swagelok Connector for Tight-place Installations Swagelok installation kit for the MMT317 includes Swagelok connector with ISO3/8" thread ( Vaisala order code: SWG12ISO38) or NPT1/2" thread (Vaisala order code: SWG12NPT12). See figure below for MMT317 with Swagelok Installation Kit.

Calibration of the MMT318 and MMT317 can be carried out by the user according to the instructions given in this chapter. The device can also be sent to Vaisala for calibration. See Vaisala Service Centers' contact information on page 47.
MMT317 is done by using two reference humidities, difference between the two humidity references must be at least 50% RH. An easy calibration can be done by using Vaisala Humidity Calibrator HMK15. If using HMK15 calibrator, please use the adapter fitting (13.5 mm) with the MMT318 and MMT317 probe.

Using these coefficients the accuracy of measurements is increased. The determined coefficients of the transformer oil can be programmed to the MMT318 and MMT317 by Vaisala or by a user according to the instructions presented on page 58 .

USER'S GUIDE____________________________________________________________________ Paper machine application Typically, a paper machine contains two or three separate lubrication systems. Usually, one is located at the wet end and the other at the dry end. There is a certain amount of free moisture constantly present which means that there is a risk of this moisture becoming into contact with the machine bearings.
