Non-Intrusive Pipe Mount, Transmitter
The ACI Transmitter Strap-On Series features a standard two-wire, 4 to 20 mA loop powered
output signal with optional 3-Wire voltage output signals available. The Strap-On transmitter
should be used in retrot applications where an immersionstyle sensor can’t be inserted into
the pipe or in applications where high accuracy is not required. For best results, ACI
recommends cleaning the pipes with a brush or small piece of sand paper before applying
thermal grease to the top of the copper plate and securing to the pipe. Be sure not to over
tighten before insulating the transmitter from the eects of the ambient air. For best results the
sensor should be mounted on the top or sides of the pipe such that moisture and condensation
will not cause the transmitter to fail prematurely. 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 specied.
Zero and Span adjustments are available for recalibration in the eld when using NIST Certied 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.
Applications: Hot Water Systems, Chilled Water Systems, Hydronic Systems, Chillers, Boilers
