PETROLEUM GAUGING THERMOMETER
The TP9 employs the proven RTD design that has been used in the TP7 and TP8 for many years. A sealed industrial quality overlay provides a user interface that is easy to use with gloves. A stainless steel enclosure protects the circuit board and large LCD from penetration by impact, water and reactive liquids.
The new TP9 circuit board is an evolutionary step up from our highly accurate, reliable and successful TL1 laboratory thermometer. The Power Button’s primary function powers the instrument for intervals of about 20 minutes since the last button was accessed. The Power Button can also be used to conserve power and clear the memory, or to make adjustment while in calibration mode. A simple menu operation is displayed by holding the Function Button, and alternately functions to allow adjustments in the calibration mode. Arrows on the left side of the display show the direction of the temperature reading and whether stability has been reached. At the user’s discretion stabilized temperatures can be logged at numerous liquid levels for a running average and later displayed for the user’s documenting purposes. But this feature never interferes with simply getting an accurate temperature reading.
To endure the environment and be intrinsically safe, the TP 9 is manufactured of materials, which are both immune to petrochemicals and are non-sparking. The enclosure is made of stainless steel. The probe assembly is constructed using non-stick cable and stainless steel sensor components.
