  • Heat Payment: 0o so you can 45oC (32o so you’re able to 113oF) ±dos.5% precision -20o to 0oC and 45o to 65oC (-4o so you can +149oF and you may 112o to help you 148oF) ±5.0% reliability
  • Height Payment: Below water-height to at the least ten,one hundred thousand foot.
  • DIMENSIONS: 2-1/cuatro ins strong x cuatro-1/cuatro inches highest x 4 inches large (5.7 centimeters strong x ten.8 centimeters highest x 10.2 centimeters wide). Dimensions tend to be switch security however, prohibit hose pipe barb and strip video.
  • WEIGHT: 23 oz. (652 grams)
  • CASE: Case vinyl are electrically conductive to attenuate radio-frequency disturbance; an optional leather-based instance can be found to own push security through the crude use eg underground exploration or framework and you can demolition really works areas
  • SERIAL Matter Personality: Found on the side of the case under the electric battery (tend to be count within the communication that have Zefon)

Functional Description from Procedure

The latest Companion ELF Push includes a rechargeable-battery prepare, a system-passionate push, the newest ELF alarm, while the digital circuit to manage and monitor new circulate rates.

The fresh new tissue are linked within the series which have a recent limiting resistor so that include in risky atmospheres (discover “Warnings”). The newest package has also good PTC resistor and therefore serves as good self-resetting routine breaker to prevent harm to brand new pack in the event the efficiency terminals are accidentally shorted. A great thermal cutoff handles up against wreck regarding high temperature standards inside the the newest NiMH electric battery.

The fresh new motor-passionate push consists of an inlet pulsation dampener, a good diaphragm pump, and silicon rubberized inlet and you can exhaust valves. The fresh new diaphragm was inspired of the system to make one to pump coronary attack with each trend. The new pulsation dampener acts as an elastic shops chamber to easy the person pump pulses to attenuate the impact on this new sampling gizmos linked to the pump inlet.

The newest ELF detector include an excellent laminar flow function and you may an excellent pressure alarm. Most of the air flow from push seats throughout the fatigue port of the push and from laminar-flow ability. The fresh ability is actually an empty cylinder from permeable stainless. The atmosphere flowing from the slim passages throughout the tube produces an environment pressure difference in the latest external and you may inner walls of the brand new tube. Which difference is actually tracked because of the connections to the new highest and you can low pressure taps out-of a painful and sensitive differential tension sensor. The electronic signal regarding alarm is a beneficial linear current, that’s in person linked to the air move through the laminar function. That it code is actually compared to circulate lay part of the new electronic circuit which will be always handle new disperse within place area. One deviation from inside the flow speed is actually noticed additionally the motor power was modified in order to maintain new predetermined flow speed. In the example of a blocked move otherwise operation outside the push capacity the spot where the circulate can’t be brought to contained in this ±0.step one LPM of the set part, the fresh flow fault Contributed would be lighted.

Added Signal Process

  • The fresh Work on/Keep Led guarantees an individual your unit was working, in improperly lighted, noisy surroundings.
  • The latest Focus on/Keep Led including indicates the Hold mode. If your pump try turned to hold, the push shuts down, the fresh timer comes to an end, plus the Contributed was transformed to a flashing setting. In the event the Work with/Keep switch is actually pressed once again, this new push tend to resume and timer is going to continue from its “hold” value.
  • The reduced BATT Provided implies process of your lower electric battery identification routine. When the battery power drops to cuatro.step one volts, the fresh new circuit factors the brand new push to close down, the fresh timekeeper to avoid, and also the Reasonable BATT Contributed to light. This constraints next electric battery drain to just a few milliamperes, and therefore, consequently, aids in preventing deep discharging and you can electric battery wreck upon recharging. It also helps avoid the invalidation of the test being taken, because the timer areas the true decide to try some time and this new disperse speed is actually controlled up to committed regarding close-down.
