3 Three or Five-Wire Mode Connection FOR INTRINSICALLY SAFE SENSORS IN HAZARDOUS ATMOSPHERES The following discussion about three and five wire mode connections, between the X005 Galvanic Isolation and sensor, is intended as an aid for end-users who are not familiar with the topic. Whether opting for a pre-wired Positek Intrinsically Safe sensor or one with a connector, choosing the right mode of connection and cable to suit the application requires careful consideration. Conductor resistance, a function of conductor cross-section, cable length and temperature, causes volts drop across a cable. As the term implies cables do not transmit the voltage perfectly, depending on material resistivity, conductor cross section and the current drawn from the power supply the voltage at the end of the cable will be less that at the power supply. This can significantly alter the perceived accuracy of the sensor which is ratiometric i.e. the output signal is directly affected by the supply voltage at the sensor. It should be noted that volts drop calculations consider the current flow return path so the cable length is multiplied by two. Three wire mode connections are common and are suitable in most cases with short or moderate cable runs. Applications that do not require a high degree of accuracy but have cable runs, say in excess of 50m, volts drop can reduced by introducing a terminal box close to the sensor and using a larger cross-section cable with for a majority of the intended cable run. Another factor to consider is conductor temperature. Fluctuations in temperature cause minor changes in resistance, the effects of which will be seen as gain variation in the sensor output. s supplied with cable are calibrated with the cable fitted which negates errors due to conductor resistance at room temperature; however, small gain errors due to temperature fluctuations in the cable should be expected. There are instances where large cross-section cables are not practical; for example most standard industrial connectors of the type used for sensors have a maximum conductor capacity of 0.75mm 2, copper prices and ease of installation are other considerations. Five wire mode connections have significant benefits over three wire mode as losses in the power and ground conductors are compensated for, thus smaller cables can be used. The Galvanic Isolation senses and dynamically adjusts the output voltage so that the voltage at the sensor is correct, the effects of cable resistance and associated temperature coefficients are eliminated. The X005 amplifier can compensate for up to 15Ω per conductor with a current flow of 15mA, which is more than adequate for 150m of 0.25mm 2 cable. For this reason Positek recommends five wire connections for cable lengths exceeding 10 metres in 0.25 mm 2 cable to preserve the full accuracy of the sensor. See illustrations right for examples of connecting a sensor to the Galvanic Isolation. The X005 will compensate for up to 15 ohms resistance in each conductor, this imposes the following minimum cable sizes:- 0.75mm² max. Cross Section (mm 2 ) Cable Length (metres) 0.25 Up to to to to to to 1000 It should be noted that the maximum cable length as specified in the sensors certification takes precedence and must not be exceeded. The above lengths and conductor sizes used in a three wire connection will introduce a gain reduction of 5% and a ±1% temperature dependence of gain over the range -40 C to +80 C for the cable temperature. (i.e. about 150 ppm/ C for the maximum lengths shown and less pro rata for shorter lengths.) M100-17j 3 of 3

12 Three or Five-Wire Mode Connection FOR INTRINSICALLY SAFE SENSORS IN HAZARDOUS ATMOSPHERES The following discussion about three and five wire mode connections, between the X005 Galvanic Isolation and sensor, is intended as an aid for end-users who are not familiar with the topic. Whether opting for a pre-wired Positek Intrinsically Safe sensor or one with a connector, choosing the right mode of connection and cable to suit the application requires careful consideration. Conductor resistance, a function of conductor cross-section, cable length and temperature, causes volts drop across a cable. As the term implies cables do not transmit the voltage perfectly, depending on material resistivity, conductor cross section and the current drawn from the power supply the voltage at the end of the cable will be less that at the power supply. This can significantly alter the perceived accuracy of the sensor which is ratiometric i.e. the output signal is directly affected by the supply voltage at the sensor. It should be noted that volts drop calculations consider the current flow return path so the cable length is multiplied by two. Three wire mode connections are common and are suitable in most cases with short or moderate cable runs. Applications that do not require a high degree of accuracy but have cable runs, say in excess of 50m, volts drop can reduced by introducing a terminal box close to the sensor and using a larger cross-section cable with for a majority of the intended cable run. Another factor to consider is conductor temperature. Fluctuations in temperature cause minor changes in resistance, the effects of which will be seen as gain variation in the sensor output. s supplied with cable are calibrated with the cable fitted which negates errors due to conductor resistance at room temperature; however, small gain errors due to temperature fluctuations in the cable should be expected. There are instances where large cross-section cables are not practical; for example most standard industrial connectors of the type used for sensors have a maximum conductor capacity of 0.75mm 2, copper prices and ease of installation are other considerations. Five wire mode connections have significant benefits over three wire mode as losses in the power and ground conductors are compensated for, thus smaller cables can be used. The Galvanic Isolation senses and dynamically adjusts the output voltage so that the voltage at the sensor is correct, the effects of cable resistance and associated temperature coefficients are eliminated. The X005 amplifier can compensate for up to 15Ω per conductor with a current flow of 15mA, which is more than adequate for 150m of 0.25mm 2 cable. For this reason Positek recommends five wire connections for cable lengths exceeding 10 metres in 0.25 mm 2 cable to preserve the full accuracy of the sensor. See illustrations right for examples of connecting a sensor to the Galvanic Isolation. The X005 will compensate for up to 15 ohms resistance in each conductor, this imposes the following minimum cable sizes:- 0.75mm² max. Cross Section (mm 2 ) Cable Length (metres) 0.25 Up to to to to to to 1000 It should be noted that the maximum cable length as specified in the sensors certification takes precedence and must not be exceeded. The above lengths and conductor sizes used in a three wire connection will introduce a gain reduction of 5% and a ±1% temperature dependence of gain over the range -40 C to +80 C for the cable temperature. (i.e. about 150 ppm/ C for the maximum lengths shown and less pro rata for shorter lengths.) M111-17i 3 of 3
