1Introduction

1.1 General The 8000 Series uses TERPS (trench etched resonant sensor)

technology. The RPS 8000 produces a frequency and diode voltage output. The DPS 8000 includes a microprocessor to produce a serial digital output.

Figure 1 TERPS General view

1.2 Configuration The following variables are specified at the time of ordering.

a. Pressure range b. Pressure connector c. Cable length d. Option A - Increased accuracy e. Accessories

i. User Manual (this publication) ii. Calibration certificate.

2 Installation TERPS 8XXX is a harsh media isolated product. Isolation is achieved

by hermetically sealing the sensor chip in an oil filled chamber. The weight of this oil gives a g-sensitivity as a pressure offset error.

To calibrate the TERPS 8XXX, the unit is mounted vertically with the pressure port at the lowest point. Orientation other than this produces a pressure offset error as specified in the datasheet. The error is most noticeable at lower pressure ranges.

: The g-sensitivity will also create an error in a high vibration

Note

environment and the unit should be mounted accordingly.

TERPS 81XX is not a harsh media isolated product. There is negligible change in offset due to mounting position and vibration. Because the pressure media comes directly into contact with the sensor chip, care must be taken to ensure the pressure media does not damage the sensing chip.

2.1 Connecting TERPS to pressure source

When mounting the sensor, seal the mating surfaces. Failure to properly seal may affect performance or calibration accuracy.

Male threaded pressure connectors must not be sealed or constrained against the face at the base of the thread. The forward cone or flat face should always be used as indicated below.

Depth versions should not be used at hyperbaric pressures above 70 bar (approximately 700 m of water).
