The sensor can be installed up to 1000 feet away from its point of termination using a shielded, 18-20 gauge twisted pair cable and 24 VDC power supply. The total loop resistance should not exceed 900 ohms.

While the 4 mA and 20 mA set point calibration is not fundamentally required, it's generally recommended because it optimizes the sensor's installed performance. See similar questions...

The restrictors are also included with the restrictor Kit p/n A68729. Refer to Appendix page A-7 in the 3000PA instruction manual. See similar questions...

The 4-20 mA represents the sensor's measurement span. The 4 mA set point is typically placed near the bottom of the empty tank, or the greatest measurement distance from the sensor. The 20 mA set point is typically placed near the top of the full tank, or the shortest measurement distance from the sensor. The sensor will proportionately generate a 4 mA signal when the tank is empty and a 20 mA signal when the tank is full. See similar questions...

The old 10-50 mA standard lost the battle to 4-20 mA due to the following benefits: 1) The same two-wires carry both the sensor power and signal, 2) 4-20 mA is easily converted to a 1-5 VDC input via a 250 Ohm, _ Watt resistor or 1-10 VDC input via a 500 Ohm, _ Watt resistor, 3) 4-20 mA is low current and therefore has a low heating loss through the signal wire, and 4) with shielded cable, 4-20 mA is noise resistant to radiated and inducted interference. See similar questions...

The sensor can be reverse calibrated such that the 20 mA set point is empty and the 4 mA set point is full. Reverse 20-4 mA calibration can also help optimize the sensor's response time in applications with a fast rate of level change. See similar questions...

The 4-20 mA span can be calibrated by measuring the current consumption alone with a digital multi-meter or display. During the initial moments of calibration, the sensor draws 22 mA while it's acquiring the target distance. At the time that the sensor places the set point, the current will jump down to the appropriate 20 mA or 4 mA set point and the blue LED will flash. See similar questions...

Batteries with capacities of between 1800 MA and 2400 MA are suggested. These ratings relate to how long the SongBook and iSongBook will play without recharge of the batteries. See similar questions...

About 500 ft., more than enough for average house or small office. Unlike wireless NETwork solutions Avinta's NETwork, based on existing phone wires is not affected by appliances, computers, metal walls, and other potential interference factors. See similar questions...

The wireless transmission range for most of the competing stations is generally quite limited. Although transmission range is highly variable (depending not only on the surrounding physical features of the land and structures but also on the RF interference in the area), the Vantage Pro2 weather stations will almost always out perform the competition. The Vantage Pro2 will transmit up to 1000 line of sight. See similar questions...

We suggest keeping your "targets" within 20'-30', the closer the better! 15' is the best distance. See similar questions...

Answer. Student Transportation has service standards which range from door-to-door service to walk distances in excess of 400 meters. Decisions made by developers and approved by the City of Edmonton result in some neighbourhoods being designed or modified in such a way that walk distances are in excess of 400 meters. Every effort is made to provide stops within 400 meters of the student's origin or destination. See similar questions...

Initially an isolated node has a maximum service radius of no more than say 500 metres or a third of a mile. Any public spirited enthusiast(s) can however provide a dedicated public node or even a chain of unattended nodes which relay "through traffic" for other distant users, thereby extending his/her range to that of all other connected nodes.... With numerous Internet Gateways, widespead public co-operation and participation there need be NO THEORETICAL LIMIT to distances covered. See similar questions...

If the sensor does NOT receive a valid acoustic signal return, the blue LED will turn on, and the signal output will go to 22 mA until the sensor acquires the level. This is generally caused by the presence of substantial foam, vapor and/or turbulence. Click to view ultrasonic white paper. See similar questions...

If the sensor DOES receive a valid acoustic signal return, but the level falls below the calibrated 4 mA empty set point, the blue LED will rapidly flash on and off, and the signal output will go to 22 mA until the level rises back into the span. The solution is to perform a factory reset on the sensor, re-calibrate the span and place the 4 mA empty set point lower in the tank. See similar questions...

You can go 5 meters or around 16 feet from a computers USB port or from a powered USB hub to a USB device. Back To Questions See similar questions...

Net Safety recommends no more than 500 feet when using a minimum 18 AWG shielded copper instrument cable. Distances greater than 500 feet are possible by using lower gauge cable. Contact Net Safety for installations requiring distances over 500 feet. See similar questions...

It depends on the voltage and the size of wire. For instance, if AWG16 (1.3mm2, 1.25mm in diameter) is used with 12VDC for NR-TX, the maximum wire length is 1.5km. Please refer to the instruction manual for more details. See similar questions...

Ans: Cable is the primary medium for transferring data between 1394a devices To support the maximum 400 Mbps transfer rate, the cable can be no longer than 4.5 meters. For 200 Mbps transfer rate, the distance can be extended to 14 meters. See similar questions...

We recommend using distances up to 200 meters. Under ideal conditions it is possible to reach longer distances. This depends on the type of cable and the quality of the joints. Diagnostics Kit will help you find out the maximal distance between the most distant outlets, so that you still reach sufficient throughput. See similar questions...
