HART Protocol Modems

MicroLink HART protocol modems provides a simple link between a PC and HART® (Highway Addressable Remote Transmitter) devices. They are HART compliant and maintain compatibility with HART software originally developed for RS-232 modems. Included USB software drivers make the USB modem appear to your HART software as though it were connected to an RS-232 port. MicroLink modems include the PACTware FDT frame, and the fully licensed Generic HART DTM-6 software, a simple solution that works with any HART protocol field device by supporting the common practice and universal HART commands. 

The Microflex Generic DTM-6 or Device Type Manager is installed into the PACTware FDT frame providing a simple solution that works with any HART field device. The Generic HART DTM-6 and PACTware frame supports HART common practice and universal commands. Not all functions will be available but in many applications the generic DTM-6 may be the cost effective solution to your HART device configuration needs at an affordable price.

InLink modems are complete HART protocol modem modules for OEM applications. InLink modems modulates and demodulates 1200 BAUD serial data to the HART protocol and can be easily interfaced to most micro-controllers and processors. For applications that require galvanic isolation the InLink-TC provides transformer coupling to the HART loop. The InLink-CC uses capacitor coupling to the HART loop. 

RS-485 Converters

Microflex RS-485 converters easily connect to your two wire RS-485 device and convert to either RS-232 or USB. They feature auto transmit control and do not require RTS (request-to-send) for direction control. Glitch-free power up/down permits live insertion or removal. No external power supply is required as power is taken from the RS-232 or USB port. Durable rubber and stainless steel construction and simple setup makes these converters ideal for field use. USB converters includes USB and virtual serial port drivers on a CD.

Field Tools Test Equipment

Field Tools is a collection of service tools designed to make the field technician and engineers job a little easier.

The Loop Power Supply provides portable power to loop-powered transmitters. It's easy to use, includes all connection leads, and makes it simple to attach your HART protocol modem to the loop. Power is provided by three "AAA" alkaline batteries (included) so no external power source or adapter is needed. The 24V Supply makes HART device calibrations easy.

Pulse Scope turns your laptop or tablet into a powerful diagnostics tool. It can be used by field service technicians and engineers to help with troubleshooting pulse or frequency related equipment. In addition to viewing wave-forms, the software includes a counter to keep a total pulse count over extended time periods, as well as instant measurements.  Includes a 6 feet USB cable and 3 feet test leads with changeable tips.

Natural Gas Spot Sampling Equipment

Maximize the accuracy of natural gas samples using the 2KC Solutions gas sample cylinder heating system. Gas sampling regulations require that the cylinder be preheated when taking spot samples. To meet these requirements the GCH heater preheats cylinders to 140°F, cold to hot in about 10 minutes. Heaters are available for 300cc and 500cc cylinders.  Power and control can be from a portable 12 volt GCH-140 controller or the GCH-LP 120 volt AC controller with an adjustable temperature setting for lab use.

The SSV Spot Sampling Valve maximizes natural gas spot sampling repeatability and accuracy while simplifying the sampling process.  Uses only one hand valve to control the fill & empty process to significantly speed up the time it takes to get a good sample in the bottle.

Gas Meter Volume Pulser

MicroPulser™ is a precision microprocessor based dual channel flow rate transmitter designed to be installed between the meter and vertical index, or instrument on most industrial/commercial gas flow meters. MicroPulser provides high resolution flow rate information to RTU's, flow computers or any other device requiring accurate flow rate information. Flow volumes can be calculated more frequently using MicroPulser due to the 1000 pulses per revolution output. In some cases such as sampling systems or flow rate telemetry, quick updates can significantly improve overall performance and accuracy. High speed flow computers with fast sample rates can be significantly improved with the MicroPulser's high resolution.

A primary cause of pulser failure is corrosion of the index shaft and bearings.  MicroPulser uses high performance low friction lubrication free engineered-plastic bearings and a stainless steel index shaft to eliminate corrosion failures. MicroPulser provides two Cass I, Division 1, Groups C and D outputs. Clockwise and counter-clockwise for the model MP-1000, or two matched outputs for connecting to two devices at the same time such as custody transfer) for the MP-1000M. The high resolution output is produced by a dual channel optical detector and a precision slotted disk. A microcontroller monitors the detector to determine the rotation direction as well as angular movement. The direction information is used by the controller to determine the True Absolute Rate and remove false pulses produced by vibration.
