Pressure Products
New! +GF+
SIGNET 2450 Pressure Sensor with Ultra-Low Range
+GF+ SIGNET now offers an ultra-low version of the 2450 Pressure Sensor. It boasts an operational range of 0 to 10 psig. Use it with the 8450 Pressure Transmitter, with increased decimal point resolution, and this +GF+SIGNET system is ideal for measuring level in tanks!
Typical
applications include:
• UPW storage tank
levels
• Chemical batch
tank levels
• Effluent storage tank levels
With excellent zero-point stability and simple "1-point" calibration, system set-up is a breeze! Of course, proper grounding techniques are always recommended to achieve maximum measurement reliability -- especially with these very sensitive sensors. For best results, choose one of the following examples as the grounding configuration for your system.
Grounding at the Rear Terminal
Grounding at the Junction Box
All pressure
sensors now have a nion end connection, making it possible to adapt to piping
systems without the need for an NPT connection. You can also use the 3-2100 end
connector kits to adapt the sensors to PVC, PP, or PVDF piping systems. The
union connection has the benefit of significantly reducing sensor nosepiece
stress.

Tip:
In order to maximize system accuracy and simplify setup, +GF+Signet recommends
the folowing when installing 2450/8450 Pressure devices:
1.
Install the sensor in the piping system or tank
2. Ground the system as shown above
3.At atmospheric pressure, calibrate the 8450 to 0.00 p.s.i.g
