Model 1201 Temp/Humidity Sensor System

Lauren Chiari on January 18, 2024

Model 1201 Temp/Humidity Sensor System

Model 1201 smart sensors allow for the measurement of temperature and relative humidity, (RH) during an ILRT without the aid of a data acquisition system. Each compact sensor contains one temperature channel and one temperature compensated RH channel with its own CPU, memory, signal conditioning, internal calibration constants and RS-485 bus interface.

The RS-485 network allows for multiple sensors to be connected to a PC’s communications port with a single 4-wire cable string. A typical ILRT may use six strings with seven or more sensors per string. Although the sensors are physically connected in series, they are electrically connected in parallel so that the failure of any one will not affect the others.

The advantages over a conventional system

Elimination of the need for a scanner and data acquisition system.
The amount of cable and the time needed to install it is greatly reduced.
Each sensor is a complete system in itself; a single failure will not disable the entire network.
Each sensor may be subjected to an end to end calibration in the laboratory.
The sensor directly outputs a digital signal, cable length has no effect upon the sensor's accuracy.

Replace with The Model 9623-H₂O, hydro leak rate testing machine.

Description:

9623-H₂O Hydro Leak rate Monitor.

The Model 9623-H₂O is an easy to operate system designed to be used This monitor allows for the precision testing of water tested containment isolation valves using plant demin or service water. This unit comes with 2 or three flow ranges, depending on your site-specific needs and two pressure channels, one to monitor inlet pressure and one for your test pressure.

The 9623-H₂O quantifies the component under test’s leakage rate by maintaining a constant water pressure against the barrier being tested while measuring the water flow rate needed in order to maintain that pressure constant. A steady supply at a constant pressure of clean water is required to operate.

Check Nozzles

Available Sizes:

Just screw a check nozzle into the test port of the 9623-07 and set the monitor pressure to the test pressure labeled on the Nozzle Check. The 9623-07’s Nozzle Check Screen will tell you if the measured flow rate is within tolerance to the expected flow rate labeled on the Check Nozzle. All nozzles are 1/4” or 3/8 “ NPT and made from stainless steel. Each Check Nozzle comes with a NIST traceable certificate of calibration.

NPT Check Nozzle certified to flow 26.5 scfh with a 55.0 psia inlet pressure

Pressure Decay Option

Part Numbers:9202 (Temp Sensor) & E-20 (High Accuracy Pressure Transmitter)

The quickest and most accurate way to leakage rate test a large volume, (such as airlocks) is using the pressure decay method. Graftel’s temperature sensor sensor Model 9202 can be used with high accuracy pressure transmitter to performing pressure decay tests on LRMs.

The LRM pressure decay screen reads pressure and temperature data from the 9202 and displays the leakage rate, air pressure and temperature.

Supply Air Conditioner/Pre-Regulator

Part Number: GT-1399K12

Most flow meter as found out of tolerances are due to the use of dirty, wet or oily supply air. This simple low cost device connected to the LRM inlet alleviates all of those conditions. This device both filters particles and traps any entrained oil or water from the supply air before it can enter the LRM

Max inlet pressure is 150 psig and the regulating range 0 to 125 psig.

This regulator can flow up to 1000 scfh, (approx 500 slm) at 100 psig.
