Intelligent sensor for combustible gas detection
Process engineers with a need for intelligent combustible gas detectors to protect people and equipment will find that the new modbus compatible Model S4000C intelligent gas detector is suited for chemical, oil and gas, and other hazardous environments.
The S4000C is a microprocessor-based transmitter designed for use with catalytic bead sensors. The unit features one person calibration and can virtually self-calibrate by activating a magnetic switch and applying gas. It is designed to monitor combustible gases and vapors within the lower explosive limit and provide status indication and alarm outputs.
It features a three digit digital display; 4-20 ma output; dual redundant modbus communications; warning, alarm, and fault relays; and calibration and calibration check setup modes as well as indication of remaining sensor life. All electronics are contained within an explosion-proof housing.

Wireless remote monitor
The new SE-9000 Teledata/Data2-U wireless remote monitoring system promises a cost effective wireless cellular based solution for the collection and presentation of data over a secure internet web site.
The system is designed to automatically collect analog and digital data from sensors on storage vessels and mechanical equipment at time intervals or when a fault occurs. This information is automatically sent by the system to the secure Data2-U web site using cellular technology. The data can be viewed and analyzed anytime from the internet.
The system is suited for remote data collection whether it be monitoring storage tanks at multiple facilities, managing chemical inventory levels as a part of a vendor managed inventory program, or monitoring maintenance points on isolated mechanical equipment.

Unit offers potable water for oil field uses
This firm offers a potable water system for isolated rigs, production camps, and pipeline spreads. The unit is skid mounted and measures 7 ft by 6 ft 9 in. It will provide 4,457 b/d of potable water, the company says. The system consists of an ultraviolet purifier and a large stainless steel filter with 3 in. flanges.

Self-contained fire-fighting rig
A compact go-anywhere fire-fighting rig, called Uni*Fire, is a self-contained version with capacity for as much as 7 min of all-out fire-fighting.
It carries its own dry chemical plus a pressure-propellant system so it's suited for pipelines, offshore platforms, processing plants, and storage facilities, the company points out.
Spewed out under high pressure, the dry chemical can quickly quench even stubborn blazes, the firm notes.
Along with the dry chemical and propellant, the rig includes a quick-opening control valve, 50 to 300 ft of UL-listed high-pressure hose, fast-rewind hose reel, and nozzles. Reels have manual or electric rewind; nozzles are standard, pistol-grip or Maxflow; a manual turret is optional.
Rigs carry 500-2,000 lb of dry chemical (Purple K, Monnex, A/B/C) for fighting wood, paper, hydrocarbon, or electrical fires. Propellant is nitrogen from pressurized tanks.
Depending on the application, rigs can be mounted on a skid, trailer, or pickup truck. Dry weight (without the chemical or nitrogen propellant) ranges from 925 lb to 2,300 lb.
Standard rig colors are high-visibility red, white, or yellow; special colors are also available.

Free brochure details radar level transmitter
A new, free, 4-page, full-color brochure describes the Mobrey MRL700 radar level transmitter.
The noncontacting transmitter is installed above the medium to be measured (liquid, slurry, or dry). Its antenna then emits a continuous microwave signal ramping between 9.55 ghz and 10.55 ghz and receives a reflected echo, enabling the instrument's microprocessor-controlled electronics to compute the medium's level to an accuracy of
The MRL700 features a NEMA 4X metal enclosure housing a four wire 24 v dc electronics. A 1 in. thread mounting allows for easy, low-cost installation; flange mounting is also available. The 316 stainless steel wet side provides resistance (a Hastelloy C wet side is optional), and a Teflon antenna allows use in almost all applications. Horn antennas and process seal versions are also available.
The new instrument meets US FCC requirements (Part 15 and Part 90 type acceptance) and is explosionproof in CL1, Div. 1, Groups B, C, D, E, F, and G installations.
