S2K Flexible
Sampling System
|
Description:The IST model S2K Sampling System is a flexible sampling
system which is designed to condition the sample as required. This system not only brings
the sample to the sensor, in many cases, it is the only viable solution to difficult
applications. Functions:The S2K controls the following functions:
1. External pump delay:
This is the time delay from the beginning of the cycle before the external pump is
activated. During this time, the external pump is off. The timer can be set from 0-255
minutes, with a resolution of 1 minute. Each timer is set by an eight position DIP switch with the
following count values: There is a micro-switch which activates a relay contact if there is a failure of the flow into the sensor chamber. A calibration switch with an LED indicator allows the user to perform standard calibration functions on the sensors. The S2K housing is designed to be used with standard IST 4-20 IQ sensor modules but other sensor modules (such as the SM95) can be used also.
System Specifications:Enclosure: NEMA 4X. Fig. 4 |
For
instance, in applications where the sample concentration is too high for the sensor, the
model S2K's ability to dilute samples allows the sensor to be exposed to the sample and
provide an accurate reading. Another advantage of non-continuous sampling is the fact that
the zero point is confirmed on every reading which increases the confidence level of the
measurement. Fig. 1 illustrates phosphine gas diluted at a 5:1 ratio measured on a solid
state sensor.
Fig. 2
The S2K sampling system can be configured with
a variety of options. Fig. 3 illustrates the two-stage sampling system. Figure 4 shows a
complete system with a sample diluting assembly. IST will assemble the system to meet
application requirements.

COMPUTERIZED REMOTE-LINK SYSTEMPrice - Pdf Price List's Description The Remote-Link System is a state-of the are, computer -controlled, gas monitoring system which allows sensors to communicate with the Remote-Link Computer over a data highway - eliminating the individual sensor wiring associated with conventional monitoring systems. |
 |
| The Remote-Link's powerful monitoring software
includes such features as data archiving and reporting, curve plotting, alarm processing,
and fault monitoring. Additionally, a graphics display shows a drawing of your plant and
the locations of a ll the sensors within your plant. By using the mouse button to point
and click a sensor, you can view it's current reading and alarm status. A separate screen
allows you to view the readings of all sensors simultaneously. When an alarm occurs,
audible and visual indications are provided on the computer screen, and the graphics
display will pinpoint the area where the alarm is occuring. Alarm relays are also
activated to trip horns, lights, etc. Alarm relays are fully programmable and each relay
can be assigned to a single sensor or group of sensors.

The modular design of the system enables additional sensors to be added with ease at a low incremental cost, allowing you to expand the system according to your needs. Computer assisted calibration takes the hassle out of calibration. Zero every sensor in the system with one press of a button. Then, simply apply gas to each sensor and let the computer do the rest. Calibration just doesn't get any easier than this! The Remote-Link Sytem is extremely versatile and can be configured any number of ways to suit virtually any application. It's design allows it to accommodate any size facility, and multiple display screens can be provided. Additionally, each Remote-Link Computer is equipped with an internal modem which allows IST to provide on-line support whenever necessary. The Remote-Link System can be used with either our standard sensor transmitter (SM95), our intelligent sensor transmitter (4-20IQ), or sensor transmitters from other manufacturers.

The IQ-1000 or TLV Panther accepts and simultaneously displays the readings of up to 4 sensors, giving it the flexibility to meet a wide range of applications. The IQ-1000's "Gas Search" feature allows you to use the Mega-Gas Sensor to scan an area for hazardous gases. Because the Mega-Gas Sensor can detect over 100 gases, if a gas search inidcates a zero reading, chances are that no hazardous gases are present. The IQ-1000 and TLV Panther have impressive capabilities, yet still remains convenient and easy to use. Calibration is simple and automated, with no manual adjustments necessary. The TLV Panther even has a completely automated calibration mode that allows the microprocessor to calibrate all of the active gases for the PID with the push of a button. Thus, the user can calibrate 10, 20, or even 30+ gases in less than a minute! Besides easy calibration, operation is a snap. Simply select the gases you want to monitor and the microprocessor based unit will do the rest. A large, 8 line, 40 character display allows the simultaneous display of 4 gases along with alarm and calibration information. Power is provided via 6 'D' size alkaline or nickel cadmium batteries. The IQ-1000 and TLV Panther include a built-in sample pump and sample wand, as well as a handy carrying case. Datalogging can be provided as an option, allowing the storage of months of data. An RS-232 port allows you to send data to a computer or printer. Included with datalogging is the IQ-1000's powerful EINSTEIN data management PC software.
