Digital pressure transmitters differ from their traditional counterparts in their output signal. Instead of a standard 4-20mA current loop, they provide a digital signal like I2C, SPI, or HART protocol. This allows for more complex data transmission and integration with digital control systems. Here's a breakdown of typical digital pressure transmitter specifications, incorporating elements from both analog and digital realms: General Specifications · Pressure Range: Similar to analog transmitters, this specifies the measurable pressure range (e.g., from fractions of psi to thousands of psi). · Accuracy: Expressed as a percentage of full scale (%FS). Typical accuracy remains around ±0.1%FS for good quality models. · Output Signal: This is the key differentiator. Digital transmitters use protocols like I2C, SPI, or HART to transmit digital data representing pressure readings. Performance Specifications · Temperature Limits: The operating temperature range the transmitter can withstand. · Proof Pressure: The maximum pressure it can handle without permanent damage (typically 1.5 to 2 times the upper pressure range limit). · Burst Pressure: The pressure that will cause catastrophic failure (typically 4 times the upper pressure range limit). · Response Time: The time it takes for the digital output to respond to a pressure change (usually in milliseconds). Digital Specifications · Communication Protocol: The specific digital protocol used for communication (e.g., I2C, SPI, HART). This determines how the transmitter interacts with digital systems. · Resolution: The smallest pressure change that the transmitter can detect and represent digitally. Higher resolution translates to more precise measurements. · Data Format: The format of the digital data transmitted by the sensor, which specifies how the pressure value is encoded. Environmental Specifications · Ingress Protection (IP rating): Similar to analog models, this rating indicates the level of protection against dust and water ingress (e.g., IP67 for dust tight and submersion up to 1 meter). · Material of Construction: Materials used in parts coming into contact with the process fluid (e.g., stainless steel, Hastelloy C, Monel). Additional Features · Display: Some models may have a built-in display for local pressure reading. · Calibration: Calibration is necessary to ensure accuracy. Some models offer features like zero and span adjustments for easier calibration. Factors to Consider When Selecting a Digital Pressure Transmitter · Process Connection: The type of fitting used for connection (e.g., NPT, flange, sanitary tri-clamp). · Electrical Connections: The type of electrical connector for power and data transmission. · Software Compatibility: Ensure the transmitter's protocol is compatible with your data acquisition system or controller software. By understanding these specifications and additional factors, you can choose a digital pressure transmitter that aligns with your application's requirements for accurate digital pressure measurement and seamless integration with your digital control system.

The One-Touch® Differential Pressure Transmitters are cost-effective, compact transmitters that reduce up front costs as well as expenses over the life of the product. These instruments not only alleviate cumbersome turn pots typically found in most transmitters, but eliminate entirely the need to span the instrument during calibration. With a single digital push button, both ZERO AND SPAN are calibrated properly, nothing else is required. No additional reference pressure sources and separate calibration devices are necessary; no need to remove from service and send to a lab. All that is required of the installer or user is to let the unit sit at zero reference pressure, then push a button. That is it! The transmitter is now ready for operation. Time savings are enormous over the life of the product compared to traditional transmitters which require time to annually remove the product from service plus the additional time to actually perform a complete full-span calibration. Mounting is simple with integral mounting holes on the 616KD that are inherent to the molded housing. The 616KD has the expanded capability to be mounted on a 35mm DIN rail either via its side or back integral DIN rail clips. The Series 616KD has easy-to-wire open screw terminals at the top of the housing. An optional protective cap snaps directly to housing to cover terminals. The One-Touch® family of Differential Pressure Transmitters are ideal for building automation applications such as air handlers, duct pressure, variable air volume and filter monitoring. Available models include ranges from 1 in w.c. to 20 in w.c. depending on series.
