The ACI Transmitter Board Only Series features a two-wire, 4 to 20 mA loop powered output signal with optional 3-Wire voltage output signals available. Sensors are not included with the board only transmitter since they are designed to be used with any existing 100 or 1000 Ohm Platinum RTD sensor with a 385 temperature coefficient. All transmitters must be ordered with the temperature span that you require, since the boards are tuned to give you the best performance characteristics for the temperature span specified. Zero and Span adjustments are available for recalibration in the field when using NIST Certified equipment. ACI recommends the use of an 18 to 22 AWG shielded cable for all temperature transmitter installations to protect against the introduction of noise onto the signal lines. For applications in which a much you are looking for increased temperature performance and a higher level of corrosion and moisture resistance, our Ruggedized (Thermally Conductive Epoxy Coated) transmitters are also available. ACI does offer recalibration services for any transmitters sent back to us for a nominal fee. Applications: Replacement Temperature Transmitters, High Moisture and Corrosive Environments, Conversion of existing Platinum 2 or 3 Wire RTD’s to linear current or voltage output signal, transmit signals over long wire runs
