MECHANICAL INSTRUCTIONS
1.1 PROCESS FLUID FITTING
Mechanical Instructions
When removing or attaching the microcap to the pressure sensor, follow the procedures below:
Removal
1. Use a 11/16” hex wrench on the process end fitting and a spanner wrench (McMaster PN: 5472A1)
2. Turn the 11/16” wrench counter-clockwise to loosen.
3. Avoid if possible scraping angled metal surface and PTFE O-ring groove with metal parts or
process fitting threads.
4. Take care to ensure the you do not touch the membrane as it is fragile.
5. If cleaning is necessary, use Isopropanol/ acetone or other solvents to rinse the membrane
without contacting it.
6. prelace PTFE O-ring after process end fitting is removed without scratching gland surfaces.

*Note: The O-rings in the above table are not compatible with acetone.
1.2 CONSUMABLES
The following 0-rings may need to be replaced during the life of the sensor:

1.3 MICROCAP ATTATCHMENT
Feedthrough Spanner
11/16” Hex Wrench Membrane
*DO NOT TOUCH*
Figure 1-2. Microcap Attatchment
PTFE
1. Heat PTFE O-ring to 100°C for easier installation of O-ring.
2. Take care to ensure the you do not touch the membrane as it is fragile.
3. Engage the threads by hand while gently pushing the process end fitting.
4. Use a 11/16” hex wrench on the microcap and a spanner wrench on the feedthrough.
5. Turn the 11/16” wrench clockwise. Hand tighten process fitting to feedthrough end.
6. Torque to 40 N•m, do not over torque as this may damage metal to metal seal.
7. Gap between lip of process fitting and feedthrough should be approximately 0.02”.

2.5 LIFE TIME EXPECTANTCY NOTE:
Operating at extreme temperatures can and will dramatically reduce life expectancy. The expected
lifetimes above were observed in a dry environment where both the electronics and pressure fittings
were subject to atmosphere. XS-HTI-4 is not rated for operation beyond 175°C and 10000psi; accuracy
and quality will not be guaranteed.
2.6 FREQUENCY RESPONSE NOTE:
An increase in pressure applied to the sensor will result in a decrease of the pressure oscillator
frequency (approximately 3 PSI/Hz). Transient temperature effects will influence the pressure oscillator
frequency. Therefore, the temperature oscillator is used in tandem. An increase in temperature of
the sensor will result in an increase of the temperature oscillator frequency (approximately 0.1°C/Hz).
Pressure readings during temperature stability will result in optimal performance.

To start interfacing with the XtalX pressure transducer begin by:
1. Using a FTDI Serial Cable or preferably the provided TTL-232R-3V3 FTDI cable connect to the
Sensor male DIP pins Pushing The brown Male pin into the Black Female port on the FTDI Cable.
If there is no male header attached to the DDQS transducer, follow the following Silk Screen to
FTDI color connection Matrix when soldering and or connecting to your FTDI cable.
