Wireless data transmission system is explosionproof, battery powered
This new, battery-powered, wireless transmission system measures temperature and pressure.
The explosionproof system is designed for measuring and transmitting temperature and pressure signals out of a Division 1 area to a safe area. A NEMA 4X version is also available for nonexplosionproof applications where ruggedized, waterproof protection is required.
The system comes with a ruggedized explosionproof Division 1 or NEMA 4X enclosure, thermocouple, RTD, or pressure transducer inputs, self-contained lithium battery, radio transmitter, and antenna. A receiver unit is also included, which can be installed in any of the firm's cast aluminum, fiberglass, or stainless steel enclosures.
Features include:
Approval for Class I, Division 1 or industrial locations.
Signal conditioning for thermocouple, RTD, or pressure transducer inputs.
Range as far as 3,000 ft with no line of sight.
Ease of use, battery powered; no setup or programming required.
Data transmit interval set in the range of 1-60 sec.
Frequency Hopping Spread Spectrum technology.
License free 902-928 MHz ISM band.
Adjustable transmit power from 1 mW to 1 W.
Available inputs: thermocouple, RTD, or transducer.
Available outputs: RS-232, 4-20 ma, 0-5 V.
Glass dome for maximum RF signal transmission and visual inspection of status LED's.

Tool helps prevent paraffin blockage
A new in-line heater, when integrated into any piping system, provides a permanent heat source directly in the production strand, flowline, field line, or pipeline—onshore and offshore. The heater can also be used in holding tanks and cargo ships.
The unit can be utilized in flowing well and pumping wells and is designed in such a manner as to allow rods to function normally through it.
The heater comes standard in 50 ft length.
