The USB MicroLink HART modem provides the hardware interface between Highway Addressable Remote Transducer devices, HART^®, and a Windows^® PC with a USB port. Universal Serial Bus (USB) drivers make MicroLink compatible with most software developed for RS-232 serial port interface modems. MicroLink appears as an RS-232 Com port to your software. A rugged design makes MicroLink an ideal choice for field engineers and technicians who service HART devices in an industrial environment. MicroLink is compatible with all certified HART devices and all leading HART configuration and monitoring software that us an RS-232 serial port for the interface.

The 101-0020 USB to RS-485 Converter provides a simple, low cost interface between a PC or laptop with a USB port, and 2-wire RS-485 devices. Universal Serial Bus (USB) drivers make this converter compatible with most software developed for RS-232 serial port interfaces because it appears as an RS-232 port to your software. Switching between receive and transmit is automatically controlled, RTS (request to send) is not needed. Power for the converter is taken from the USB port so no external power supply is required. A rugged design makes 101-0020 an ideal choice for field engineers and technicians who service RS-485 2-wire equipment in an industrial environment. Because the 101-0020 RS-485 converter can be used on devices without a ground terminal, voltage suppression is used to clamp the common mode voltage to +/- 7 volts for increased protection.

The SSV Spot Sampling Valve maximizes natural gas spot sampling repeatability and accuracy while simplifying the sampling process. It fits between the sample probe and sample cylinder and includes the liquids separator, bypass vent valve, fill & empty valve, and extension tube pigtail with flow regulating port - recommended by the GPA 2166 standards for best accuracy. Field testing has proven that using the SSV with heated sample bottles provides consistent accurate samples. It can be used with the helium-pop or fill & empty sampling methods.
