1. Specification
The Pirani vacuum gauge sensor unit SW100 is a vacuum gauge that can measure the
low vacuum pressure by connecting a dedicated sensor (SWP series).
SW100 is the next model to the conventional model SW1. SW100-A is compatible with
SW1-1, and SW100-R is compatible with SW1-2.
The following two types of interfaces are available. You can select the
specification that best suits the communication type.
Analog output type : SW100-A (Next model of SW1-1)
Serial communication type : SW100-R (Next model of SW1-2)
(Hereinafter, SW100 refers to both SW100-A and SW100-R.)
The I/O connector of SW100 uses a D-sub 15pin and USB Type-C.
SW100 is set with the dedicated Windows/Android application "UL-MOBI".
※"UL-MOBI" can be downloaded from our homepage or Google Play. For details,
refer to the SW100 instruction manual.
※USB Type-C can be connected to a Windows/Android device with UL-MOBI installed
using the USB cable, and can be monitored and set by UL-MOBI.
※UL-MOBI for Windows requires a Windows device with a USB device driver
installed. For details, please refer to the SW100 instruction manual.
※Settings that require UL-MOBI are SET POINT, OUTPUT, ADDRESS, BAUD RATE, and
CHECKSUM. For details, please refer to the SW100 instruction manual.
※Windows/Android devices and USB cable are not included.

The SW100-A maintains the compatibility (OUTPUT) shown in this chapter for the
measured output voltage. By using this function, it can be replaced with SW100-A
without changing the setting to convert the measured output voltage from SW100-A
to the pressure value on the equipment side.
The setting of this function can be easily set with the dedicated application
"UL-MOBI".
OUTPUT Compatible models/conversion formula
SP1 ULVAC Pirani vacuum gauge sensor unit SP1
PSG P=10^((V-3.572)/1.286)
(P：Pressure[Pa]、V：Measured output voltage[V])
APG P=10^(V-4) (P：Pressure[Pa]、V：Measured output voltage[V])
After purchase, please check the instruction manual of SW100 for both new
installation and replacement, and set and connect. When used as a compatible unit,
the performance of SW100-A may be limited, so please read the instruction manual.
※"UL-MOBI" can be downloaded from our homepage or Google Play. For details,
refer to the SW100 instruction manual.
※To set SW100, a Windows/Android device with the application "UL-MOBI" installed
and a USB cable (SW100 side: Type-C) are required.
※UL-MOBI for Windows requires a Windows device with a USB device driver
installed. For details, please refer to the SW100 instruction manual.
※ULVAC display unit ISG1 does not support the measured value output voltage
conversion formula of PSG and APG.
※If the specifications of the I/O connector are different, you need to change
the connector.
※If you set the SW100 on the equipment side, you do not need to use the
compatibility function in this section.

Measurement value output
This unit outputs the measured value as a voltage signal of DC 0V to 10V.
I/O connector: 8pin[Measured value output+]-15pin[GND]
※When SP1, PSG, APG is selected as OUTPUT (see Section 1.4 of this manual), the
specifications are followed instead of the voltage output and pin sign in this
section. For details, refer to the SW100 instruction manual.
Use the following formula to convert to pressure.
P = 10 ^ ( V - C ) ⇔V = log P + C
P: Pressure V: Measured output voltage[V] C: Conversion factor
Pressure unit C: Conversion factor
Pa 3
Torr 5.1249
mbar 5
※When SP1, PSG, APG is selected as OUTPUT (see Section 1.4 of this manual),
follow the respective conversion formulas instead of the pressure conversion
formulas in this section. For details, refer to the SW100 instruction manual.
Measurement value output
The table below shows the measurement value output under some conditions that
can occur during measurement.
Operating state Measurement value output voltage
Normal measurement DC 1.7V to 8.0V
Higher than atmospheric pressure DC 8.0V or more
Below measurable lower limit DC 1.0V to 1.7V
Filament disconnection DC 9.0V or more
4 seconds after startup DC 8.1V
※When SP1, PSG, APG is selected as OUTPUT (see Section 1.4 of this manual), the
value will correspond to each conversion formula, not the output voltage in
this section. For details, refer to the SW100 instruction manual.
