Installation
3.9.6 The 32003 insertion/extraction valve
The ORBISPHERE 32003 insertion/extraction valve (illustrated below) allows for sensor
removal and installation without having to drain the fluid in the line. It can withstand a pressure
of up to 20 bars, with the sensor in place or not.
Sensor insertion is made by inserting the sensor into the housing and tightening the retaining
collar until it stops. As the retaining collar is tightened, the valve will open to allow the sample to
flow past the sensor head. Remove the sensor by unscrewing the collar and pulling the sensor
out. As the collar is unscrewed, the valve will automatically close to avoid any sample spillage.
The diagram above right, shows the sensor in a sample line with the valve open.
Note: This insertion/extraction valve is only available for the M1100-S00 sensor and cannot be used with
the M1100-S10 sensor.
3.9.7 The 33095 and 33096 sensor housing
Two other types of sensor housing are available for use with the M1100 sensor but require that
the sample flow be turned off prior to insertion or removal of the sensor.
These are the ORBISPHERE 33095 housing (for use with the M1100-S00 sensor) and the
ORBISPHERE 33096 housing (for use with the M1100-S10 sensor).
Sensor insertion is made by inserting the sensor into the housing and tightening the retaining
collar until it stops. Removal is made by unscrewing the collar and pulling the sensor out. Be
sure that the sample flow has been turned off before inserting or removing the sensor.
Note: The M1100-S10 sensor has a PG-13.5 12 mm diameter fitting and can be inserted directly into any
existing compatible fitting.
3.9.8 Tuchenhagen Varivent® in-line access unit
The following illustration shows the Tuchenhagen Varivent® In-Line Access Unit.
Purchasing a Tuchenhagen Varivent® in-line access unit, or an equivalent fitting with a 68 mm
flange diameter from the fitting manufacturer, is required to make use of the ORBISPHERE
model 32003, 33095 or 33096 sensor housing devices detailed above.
