|
| ||
| Operating Distance | Range of distance measurement, or maximum distance measured. | ||
| Search Logic: | User may specify either, both, or neither of the "At Least" and "No More Than" values. Products returned as matches will meet all specified criteria. | ||
| Accuracy | Accuracy describes the percent deviation from the actual/real value of the measurement | ||
| Search Logic: | User may specify either, both, or neither of the "At Least" and "No More Than" values. Products returned as matches will meet all specified criteria. | ||
| Operating Temperature | The temperature range over which the device must operate. | ||
| Search Logic: | User may specify either, both, or neither of the "At Least" and "No More Than" values. Products returned as matches will meet all specified criteria. | ||

| ||
| Your choices are... | |||
| Current Balance AC-AC | Based on changes in current. AC-in, AC-out. Measures the relative currents in the two coils as a function of core position. | ||
| Current Balance DC-DC | Based on changes in current. DC-in, DC-out. | ||
| Frequency Based | Based on changes in frequency. Measures the resonant frequencies of the coils as a function of core position. | ||
| Search Logic: | All products with ANY of the selected attributes will be returned as matches. Leaving all boxes unchecked will not limit the search criteria for this question; products with all attribute options will be returned as matches. | ||

| Output | |||
| Your choices are... | |||
| Switched / Alarm | An "output" of a change in state of switches or alarms | ||
| Voltage | Output voltage is a simple (usually linear) function of the measurement. | ||
| Current | Often called a transmitter. A current is imposed on the output circuit proportional to the measurement. Feedback is used to provide the appropriate current regardless of line noise, impedance, etc. Useful when sending signals long distances. | ||
| Frequency | The output signal is encoded via amplitude modulation (AM), frequency modulation (FM), or some other modulation scheme, but the signal is still analog in nature. | ||
| Search Logic: | All products with ANY of the selected attributes will be returned as matches. Leaving all boxes unchecked will not limit the search criteria for this question; products with all attribute options will be returned as matches. | ||
| Interface | |||
| Your choices are... | |||
| Serial | A standard digital output protocol (serial) such as RS232, etc. | ||
| Parallel | A standard digital output protocol (parallel) such as IEEE488, etc. | ||
| Search Logic: | All products with ANY of the selected attributes will be returned as matches. Leaving all boxes unchecked will not limit the search criteria for this question; products with all attribute options will be returned as matches. | ||
