PRODUCT USER GUIDE

Product Overview

The ThermoVault Max is an extreme, high temperature

thermal barrier designed for use with the HiTemp140

series. This durable thermal barrier can withstand

temperatures up to +400 °C in dry heat applications and

+250 °C in wet applications when used with the TMAX Wet

Seal Kit (optional accessory).

Compatible Data Loggers

• HiTemp140-M12

• HiTemp140-FP

• HiTemp140-PT

Getting Started

Dry Applications

The HiTemp140-FP, HiTemp140-PT HiTemp140-M12 can

be used for dry applications up to +400 °C.

1. Unscrew the lid of the

thermal barrier.

3. If using the HiTemp140-M12

data logger, screw the

probe into the bottom end

of the barrier lid.

4. Slide the data logger and

lid back into the barrier

body and screw the lid

Wet Applications

For use in wet applications, the TMAX Wet Seal Kit (sold separately, optional accessory) should be used with the

HiTemp140-FP, and HiTemp140-PT data logger. When used in wet applications the maximum operating environment

cannot exceed 250 °C (482 °F).

Installing the O-Ring: The O-Ring ensures a tight seal which prevents liquid from entering the inside of the barrier. O-Ring

maintenance is a key factor when properly caring for the ThermoVault Max. Please refer to the application note “O-Rings

101: Protecting Your Data Logger,” found on the MadgeTech website, for information on how to prevent O-Ring failure.

The TMAX Wet Seal Kit Includes:

• PTFE Thread Sealing Tape

• Fitting Body

• Dome Nut

• Compression Ferrules: PTFE (5), Stainless Steel (1)

• O-Ring

1. Unscrew the endcap of the

thermal barrier.

2. Stretch the O-Ring over the

endcap so it sits in the groove just

beneath the knurled shoulder.

Securing the Compression Fitting: The compression fitting is used with the HiTemp140-FP and HiTemp140-PT data

loggers to ensure a water tight seal.

Compression Ferrule Note: The

stainless steel Ferrule provides the

most reliable seal, but becomes

permanent crimped onto the probe.

The PTFE Ferrule will become more

deformed with multiple uses and will

eventually require replacement. It’s

benefit is that it allows easy removal

and repositioning of the probe.

1. Wrap the provided PTFE thread

sealing tape around the Fitting

Body threads.

2. Screw the Fitting Body into the

end of the stopper assembly

(finger-tight).

3. Holding the smooth metal end of

the stopper, use a 7/16” wrench

or socket to tighten the body into

the stopper.

4. Insert the Compression Ferrule

into the Fitting Body and hold it in

place loosely with the Dome Nut.

5. Feed the data logger probe throw

the Compression Fitting until

the base of the probe is tightly

against the Dome Nut.

6. Tighten the Dome Nut to secure

the data logger in place (finger-

tight).

7. Insert the data logger and stopper

assembly back into the thermal

barrier and screw the endcap

of the thermal barrier until the

O-Ring is no longer visible.
