ETI + Pressure

ETI + Pressure

The ETI+Pressure is a high quality digital temperature and pressure-indicating device designed for displaying and documenting the processing temperature and pressure in retorts. It complies with FDA 21 CFR Part 113, and it is ideal for thermal processing of low-acid canned foods. The ETI+Pressure has a digital display that is easy to read, offers an temperature accuracy of +/- 0.1°C and an pressure accuracy of 0.15% full scale (20.....120 °C), and does not constitute a potential source of mercury contamination.

Compliant with FDA 21 CFR Part 113

  • FDA compliant alternative to mercury-in-glass thermometers
  • Dual probe temperature sensor
  • Pressure sensor  
  • Interchangeable sensors
  • NIST traceable (or equivalent) calibration certificate
  • In-house calibration with full documentation
  • Remote display option (1,200 m / 3,900 ft.)
  • Rechargeable backup battery
  • Output channel for automatic alarms

Documented and Traceable Accuracy

The ETI+Pressure accuracy of +/- 0.1°C / 0.18°F is tested against an accurate calibrated reference device and is delivered with a NIST traceable (or equivalent) calibration certificate. The ETI+Pressure temperature sensor has a unique ID which is shown on the calibration certificate ensuring traceability.

The combination of full compliance with FDA regulations and Ellab's renowned quality and high reliability makes the ETI+pressure an excellent choice for retort monitoring. Recognizing that product safety, quality and efficiency are critical to our clients, Ellab has added additional features to the ETI+pressure.

Calibration
The factory recalibration procedure is made simple as the sensor holds both calibration constants and ID which are independent from the display. When sending the sensor in for factory calibration, a certificate will be issued which includes all of the information needed to comply with FDA regulations and ensures the reliability and accuracy of the ETI. The calibration date is easily visible on the digital display. The ETI+pressure display automatically shows a warning 28 days before factory recalibration is due.

Data Transfer and Alarming

ETI for complete process control and monitoring. The new firmware enables connection to a PLC using Modbus communication.

New firmware:

  • Modbus communication.
  • Connection to PLC.

The ETI is connected to the PLC through a Modbus RTU interface. The temperature, pressure and time measurements are communicated directly to the PLC. This makes is possible for the user to control the process and the machine (autoclave). Monitoring one or several ETI units is possible when the PLC is connected to a SCADA system. This ensures an accurate overview of the measurements from all ETI units installed.

Advantages:

  • ETI to PLC communication.
  • PLC controls the process.
  • Monitoring of several ETI units in one place.

ETI + Pressure Display

Resistant To Electromagnetic Interference
To prevent electromagnetic interference from affecting the accuracy of the ETI+Pressure, it is designed according to IEC 61326 requirements. Furthermore, the IP67 classification of the ETI+Pressure ensures that it is suitable for use in an industrial environment.

Easy Readable Temperature
The high quality illuminated LCD digital display clearly shows the temperature with a resolution of 0.1°C / 0.1°C °F and the pressure with a resolution of 0.002% FS as well as the calibration date and sensor ID. The display can be connected to the temperature and the pressure sensor directly or by using a cable. This flexible solution ensures that the display can be placed away from the sensors making it easy to read. An additional remote display can be connected to the ETI+Pressure and mounted in an operator room up to 1,200 m / 3,900 ft. away.

Temperature Settings
A hardware switch makes it easy to change between °C and °F.

Automatic Warnings
The ETI+Pressure display automatically shows a warning before factory recalibration is due or if a system error occurs.



 

Internal Memory
The ETI+Pressure has an internal non-volatile memory and can be used as a battery powered data logger and store up to 60,000 data points. Start time and sample rate can be set from ETISuite. When the process is complete the ETI+Pressure is connected to the PC and the data is downloaded into ETISuite.

ETI + Pressure Sensor

Detection of Loss of Accuracy
For maximum safety and dependability the ETI+Pressure uses a dual probe temperature sensor. The intelligent sensor has two independent Pt-1000 sensing elements and A/D converters. The primary sensor is compared to the second sensor and a deviation between the sensors exceeding 0.3 ºC causes an error message to appear on the display and the ETI+Pressure alarms the user.

Pressure Sensor
The pressure sensor for ETI+Pressure is based on the stable, piezoresistive transducer and micro-processor electronics with integrated 16 bit A/D converter. Temperature dependencies and non-linearities of the sensor are mathematically compensated.

Interchangeable Sensors
Since the A/D converters are integrated in the intelligent probe, the ETI+Pressure display has no impact on sensor accuracy. When having two sensors available, it is possible to use one when the other has been sent in for factory recalibration. This reduces costs and permits users to keep a constant production flow.

Flexible Installation
Multiple sensor lengths and custom fixtures are available to fit all retorts. The display is prepared for easy mounting on DIN rails, PLC cabinets and similar devices.

ETI + Pressure Software

The ETI+Pressure can be delivered with the user-friendly ETISuite software that is used for setting the clock, collecting temperature/time and pressure data and generating CSV files which can be exported to Excel. Furthermore, ETISuite offers a feature allowing the user to make in-house probe accuracy verifications that are fully documented in detailed calibration reports.

Data Transfer and Alarming
An RS485 port allows for an additional display to be connected.  It also permits the transfer of the temperature/time and pressure data to a computer or PLC system. An output channel allows for automatic alarms.

Start time and sample rate can be set from the ETISuite software. When the process is complete, the ETI+pressure is re-connected to the PC and the data is downloaded.
