Specifications and configuration
Reference — Danfoss DST P140 pressure transmitter series
| Parameter | Documented value / configuration |
|---|---|
| Documented application | Liquid-cooling data-center pressure monitoringConditions: scope: Series application statement; exact order-code specification not established |
| Sensing and body design | MEMS sensing technology with stainless-steel design and hermetically sealed media interfaceConditions: scope: Series description; wetted alloy and pressure range require order code |
| Diagnostic option | Automatic sensor-failure detection described as an optional diagnostic capabilityConditions: scope: Optional, not claimed on all DST P140 variants |
Reference — Danfoss DST P140 075G4027
| Parameter | Documented value / configuration |
|---|---|
| Gauge pressure range | 0 to 10 barConditions: scope: Old manufacturer datasheet copy; current Danfoss Design Center also lists 0–10 bar gauge for this code. Measuring span, not overpressure or site supply rating |
| Output signal | 4 to 20 mAConditions: scope: Current Danfoss Design Center also lists 4–20 mA for this exact code |
| Process and electrical connections | G 1/4 A male pressure connection to ISO 1179-2; M12 × 1 electrical connectionConditions: scope: Current Danfoss Design Center independently lists the same code's G 1/4-A and M12 × 1 interfaces; mating connector is a separate installation input |
| Supply voltage | 8 to 28 VDCConditions: scope: Series data sheet specification for the 4–20 mA option; current exact-code Danfoss Design Center lists 8–28 V DC |
Reference — Danfoss DST P140 series
| Parameter | Documented value / configuration |
|---|---|
| Wetted materials | AISI 304L and AISI 316L listed for wetted partsConditions: scope: Current Danfoss Design Center shows 304L/316L for 075G4027; coolant and seal compatibility still require application review |

Overview
The DST P140 is a manufacturer-documented pressure-transmitter series for liquid-cooling data-center circuits and other water-related duties. This catalog entry represents the pictured sensor series, not an invented site model or a confirmed supply agreement with Danfoss.
Construction and interfaces
The official series page describes MEMS sensing, stainless-steel construction and a hermetically sealed media interface. The pictured transmitter establishes its physical product class, while wetted alloy, process connector and electrical connector still depend on the selected order code.
Selection
Danfoss order code 075G4027 is listed for 0–10 bar gauge measurement, 4–20 mA output, G 1/4 A male process connection to ISO 1179-2 and M12 × 1 electrical connection. The data sheet lists 8–28 V DC supply for the 4–20 mA version. Confirm the actual code, mating cable, gauge reference and installed measurement point before specifying it.
Configuration options
Other DST P140 codes have different ranges and electrical or pressure connections; they are not interchangeable merely because they share the series name. For 075G4027, the manufacturer lists 304L/316L wetted parts. State the connector, coolant, temperature and any calibration or diagnostic requirements on the RFQ.
Application limits
The order-code values are from a Danfoss data sheet preserved by a distributor and cross-checked against Danfoss's indexed Design Center entry. The current direct datasheet URL returned 404 and the product page could not be collected by the restricted fetcher, so recheck the current revision before purchasing. The series photo does not prove the pictured unit's exact code; accuracy and coolant suitability remain conditioned on the final configuration.
