Senex DG1300-KT HVAC Air Conditioner Pressure Transmitter
DG1300-KT
The Senex DG1300-KT HVAC Air Conditioner Pressure Transmitter is a high-performance, high-stability pressure sensing solution specially engineered for commercial and industrial refrigeration and air conditioning compressors, featuring an advanced American sensor core, robust all-welded stainless steel construction, fast dynamic response, and superior anti-vibration performance for long-term reliable HVAC process monitoring.
Engineered specifically for the demanding environments of central air conditioning systems and industrial refrigeration units, the Senex DG1300-KT pressure transmitter utilizes state-of-the-art international pressure sensor component technology combined with high-reliability signal amplification and precise temperature compensation to deliver exceptional accuracy and long-term operating stability. Built with a fully welded 304/316 stainless steel housing and corrosion-resistant wetted parts, this transmitter is designed to withstand continuous exposure to common HVAC refrigerants and non-corrosive liquids, gases, or steam without degradation or zero-drift issues.
To ensure seamless mechanical integration with HVAC equipment and compressor service ports, the unit is equipped with a standard 7/16-20 UNF female pressure connection featuring a specialized quick-connect valve pin mechanism, allowing for effortless maintenance and secure, leak-free pressure tapping without loss of refrigerant. Operating on a standard 2-wire 4–20 mA DC current loop or optional 3-wire voltage outputs, the sensor guarantees high immunity against radio frequency and electromagnetic interference, delivering fast dynamic response times under severe system pulsations and heavy mechanical shock. Every unit undergoes precision laser marking for full lifetime traceability and strict quality assurance, making it an ideal choice for OEM chiller manufacturers, HVAC system integrators, and industrial climate control distributors worldwide.
FAQ
Q: What media is the DG1300-KT pressure transmitter compatible with?
A: It is compatible with various liquids, gases, or steam that are non-corrosive to 304, 316, or 316L stainless steel, including standard HVAC refrigerants.
Q: What pressure connection does the DG1300-KT feature?
A: The standard pressure connector is 7/16-20 UNF female thread with an optional specialized internal valve pin design for easy HVAC Schrader valve access.
Q: Can the signal output be customized?
A: Yes, while the standard DG1300 model provides a 2-wire 4–20mA DC loop output, 3-wire voltage output options such as 0–5VDC, 0–10VDC, and 1–5VDC are also available upon request.
Q: What is the ingress protection level and electrical connection type?
A: The transmitter features an IP65 protection rating with standard options including a 4-core shielded cable or a DIN 43650 industrial connector.
Q: Is this sensor suitable for high-vibration applications like air compressors?
A: Yes, it features an all-welded stainless steel structure and high anti-vibration and shock resistance engineered specifically for air compressors and HVAC compressor lines.
