Example:
-JUMO dTRANS p33 Pressure transmitter and level probe for use in hazardous areas (40.4753)
The type 404753 pressure transmitter measures the pressure in both corrosive and noncorrosive gases, vapors, liquids and dusts. The transmitter operates on the piezoresistive measuring principle. The output signal is a DC current that is proportional to the input pressure.
The type 404753 pressure transmitter fulfills the following requirements for equipment group II
in Zone 1 and 2 areas with an explosion hazard arising from gas (Gas).
The pressure connection (process connection) may, however, also be mounted on to zone 0.
in Zone 21 and 22 areas with an explosion hazard arising from dust (Dust)
The EC type-examination certificate is designated: SNCH 03 ATEX 3545.
The pressure transmitter can also be used as a level probe (extra code /406).

Depth/Vented Level
Depth Sensor
Hydrolab offers high-stability, custom-made pressure sensors with four range options.
Features:
- Depth measures absolute hydrostatic pressure from an internal diaphragm
- Optimized for depths down to 10m, 25m, 100m, or 200m
Benefits:
- Vented level (0-10 m) uses a sealed dryer attached to a fixed cable that provides compensation for changes in barometric pressure.

Relative pressure-type level sensing transmitter Type 681
0 ... 0.1 - 25 bar
The pressure transmitters of type 681 with piezoresistive measuring elements have compensated, adjusted and amplified sensor signals which are available as standard voltage or current outputs. In the immersion-sensor version with a salt water and oil-resistant connection cable they are specially suited for level measurement, even in the presence of corrosive liquids.
The cable incorporates a tube for compensation of the ambient pressure.
Manufactured from stainless steel, its welded construction provides a watertight seal.

OCIO is an innovative system for monitoring the fluid level inside atmospheric tanks. The system detects the static pressure generated by the fluid height by means of a tube inserted in the tank and displays the fluid level or volume. The new design and suitable solutions guarantee a reliable and repeated level indication.
The system is composed of:
A tube for detecting the static pressure. The tube with its end is inserted from the top of the tank and dipped in the fluid down to the bottom of the tank.
A control unit for level display and system management. The unit is provided with intuitive and complete software and allows the connection of two alarm or lock devices.
By means of the software it is possible to:
- set the type and the dimensions of the tank
- define the level alarms
- define the level indication
- define the unit of measurement
- calibrate the instrument
Depending on the set alarm levels, the control unit activates or deactivates the contact working as a remote switch starting the alarm devices or cutting the power supply off the connected equipment

Pneumatic tank contents gauges represent an economic solution for an accurate tank contents measurement with remote indication. The pneumatic tank contents gauge UNITOP requires no power supply, has an accuracy of ±2 % and can be installed up to a distance of 50 m from the tank. UNITOP functions safely and reliably and with millions in daily use, is well proven.
Inspite of that it was possible to incorporate into the new instrument generation a number of ideas. The new dual scale facilitates the contents supervision of rectangular and cylindrical tanks. Indication is provided in % of liquid height and is thereby in its basic form independent of the tank shape. Naturally, for all DIN-tanks and many special tanks slide-in scales with calibration in Litres are available, as are additional scales in Litres for specially shaped tanks. All adjustment possibilities and functions are clearly shown on the dial. A robust brass connection with cap nut for connecting a Ø 6 mm tube or hose ensure safe and airtight connection of the capillary line. A vent screw has now been integrated in the connector with which it is now easily possible to check the Zero position of the pointer. The measurement mechanism which is manufactured from highly stable engineering plastic is mounted separately from the instrument housing and thereby guarantees a stable Zero point and a high measuring accuracy. In addition, the instrument also houses an overpressure device and a consumption control with date indication.
UNITOP is available for use with the following liquids: Heating oil L, EL, diesel fuel, water and urea solution (AdBlue®).

Innovative system for monitoring the fluid level inside atmospheric tanks. This system detects the static pressure generated by the fluid height by means of a tube and displays the fluid level up to 4 m., the volume or filling percentage. The control unit is provided with an intuitive and complete software that allows to set 2 alarm levels (SPDT) and/or activate remote alarm devices. High accuracy (+/- 1%). Very easy installation directly on the tank or at a distance up to 50 m. far.

Enraf’s Field Display & Interface Unit (FDI) provides tank inventory information in the field, where it is needed. It is a versatile, EEx-d approved instrument with several interface options, which can even be part of W&M approved applications.
The design of the FDI is therefore based on reliable and uninterrupted data
supply in all circumstances. The unit can be used in stand alone mode using the Enraf Bi-phase Mark communication protocol for direct connection to an Enraf gauge, or any other gauge using this standard communication protocol in tank farms. The unit will interrogate the gauge and display its measured data.
To update its display in bigger installations where a remote tank inventory
system is available, the indicator listens to the communication between the field instrument and the remote system. When the communication between system and gauge fails, the FDI automatically takes over the scanning of the instrument to provide the measurement data in the field. After sensing the scanning from the system again, it returns to the original configuration.

Measurement Specialties' Ultrastable transducers are packaged for liquid level measurement. The LM series mounts externally onto a tank, and the LP series is fully submersible in water or corrosive liquids.
Description: The LM Series incorporates stainless steel and plastic isolation suitable for level sensing in water, other liquid and gas. The LM series uses a patent pending low cost stainless steel sensor in a PVC plastic fitting. The modular design is adaptable to an infinite number of plastic port variations. With high performance in a small form factor, the LM Series enables the miniaturization of high accuracy pressure and vacuum systems. The standard output is .5V to 4.5V with a 5V supply.
