Using:

Initial Training: 

1. Point out pressure, temperature and humidity readings, noting they are green;
2. Show phone number to call if anything turns red;
3. Show the date and time on the display;
4. Show how to touch the Last Review box once the display is viewed.

Advanced Training:

2. Show how to reset Max/Min by touching the screen;
3. Show how to view a chart of all data by touching any reading.
4. Note that the internal battery will ensure the display keeps collecting data during a power outage.

Alarms

If any environment condition begins to drift outside of the ‘safe zone’ it turns red, on the display and if that condition remains unsafe:
The TV2  goes into alarm mode;
     The display begins to ‘beep’ and flash the unsafe condition;
An external N/O dry contact relay closes;
Text, Email, and/or phone messages are sent;
The condition is logged.

Alarm conditions:

• High or log temperature alarm- buzzer, flashing message, closes relay, logged to memory, text, email phone call
• High or log  humidity alarm –buzzer, flashing message, closes relay, logged in memory, text, email, phone call
• High or log  pressure alarm –buzzer, flashing message, closes relay, logged in memory, text, email, phone call
• Low sensor battery – battery indicator flashes red and icon show a low percentage reading
• Sensor alarm not set – alarm disables in red appears on display
• Power outage – buzzer, screen blanks after 20 seconds, closes relay, logged in memory, text, email, phone call

TV2 Cleanroom differential pressure sensor

The TV2 monitor uses a high accuracy sensor, which continually samples the pressure, displays it, logs it and if it is below your set alarm points, sends a text or email alert.  It is a temperature compensated digital differential pressure sensor which transmits two pressures (cleanroom and ante-room) to the monitor itself where the difference in pressure is displayed in inches of water gauge – “wg or kPa.

Each pressure sensor has two clear plastic tubes which are placed in two different rooms so that the pressure in each is sensed.  Only the end of each tube is exposed to the pressure and is normally terminated in a flush-mounted wall plate fixture.

The pressure is sampled several times a second and averaged over a a longer period of time before being transmitted to the QuickCheck display where it is shown in either a green or red font depending on whether it is within your safe limits or unsafe.

Our instruments are used in hundreds of industries.  Our thousands of customers come from a wide variety of industries.

Q.  How accurate is your pressure sensor?
A.  Our TV2 pressure sensor is accurate to ±0.002″wc

Q. Can the sensors be re-calibrated locally or do they have to be returned to the factory?
A.  All sensors can be calibrated and characterized (adjusted) locally.

Q.  Is your temperature/humidity sensor one or two sensors?
A.  Our temperature/humidity sensors are combined in one sensor.

Q. How accurate is the temperature/humidity sensor?
A.  The temperature sensors is ±0.5°C and the humidity part of the sensor is ±3.0% of ±1.5%.

Q.  How far away can the sensors be located from the display?
A.  Each sensor comes with a twenty-five foot wire, which can be extended so that the sensor can be positioned up to 200 feet from the display

Q.  Can you see the differential pressure between the cleanroom and the anteroom and between the ante-room and the hall on the same monitor?
A.  Yes.  Each monitor can show the pressure from up to four sensors.

Q.  Can I see negative and positive pressure readings on the same monitor?
A.  Yes.  

Q.  Do I need different sensors for positive and negative pressures.
A.  No.  The same sensors can be used for either positive or negative pressures.

Q.  Do I mount the monitor inside or outside the cleanroom?
A.  It does not matter.  Each sensor needs to plug into the monitor but the monitor can be mounted anywhere.

Q.  How accurate are the sensors?
A.  See the ‘Technical Details’ tab.

Q.  Do the sensors need to be plugged into wall power?
A.  No.  Each sensors is powered by the monitor?

Q.  How often is the display updated?
A.  Every four seconds.

Q.  How often is data logged?
A.  This can be set to any interval between once a minute to once a day.  Each sensor can have its own data-logging interval.

Q.  Where should the temperature/humidity sensor be mounted?
A.  It needs to be in what ever area is being monitored.  Usually it is mounted in a corner of the room near the ceiling?

Q.  Where should the pressure sensor be mounted?
A.  The pressure sensor is a differential pressure sensor, meaning that it measures the difference in pressure between two rooms or areas.  The sensor has twelve-inch two clear plastic tubes.  Each tube is plugged into a passive port which is a small plastic plate with a tiny hole in the middle.  Each passive port can be mounted on the inside of the ceiling of each area being compared.  The sensor itself can be placed above the ceiling. 

Q.  How safe is the logged temperature, humidity, and pressure logged data?
A.  Logged data is stored in non-volatile memory in the monitor.  It can also be automatically backed up to a computer.  

Q.  Do you have iq/oq protocols for qualification of these units once installed?
A. IQ and OQ documents with check lists can be accessed on our website here:  IQ, OQ Docs.

Q.  If your SMS and Email TLS1.2 compliant?
A. Being TLS1.2 compliant is dependent on a couple of different things.

1. What version of .net framework is used to compile our TView software. We use the latest version of .net (4.7.1). This insures compliance.

2. The email and text alert portion of the TView software uses SMTP protocol. So if you are using your own SMTP server to do that, the compliance for TLS is based on the configuration of your server.
