TRANSMITTER DESIGN
The basic transmitter components are: an housing made of 316 (1.4401) stainless steel or aluminum, measuring head where a pressure signal is converted to an electrical signal, and an electronic module converting the signal from the head to an output signal. Transmitters in aluminum housings are allowed for II and III group, and transmitters in steel housings are allowed for I, II and III group.

ELECTROSTATIC HAZARDS
The paint, plastic nameplate and diaphragm seals coated with PTFE form a non-conducting layer applied on a conducting base of housing or diaphragm seals. Transmitters with this design in a dust-explosion zone should be installed in a place where electrostatic charging is impossible, in particular by contact with electrically charged dust falling off or blown from neighboring devices.

SPECIAL CONDITIONS OF USE

In hazardous zones of dust explosion, transmitters with painted housings, as well as transmitters equipped with plastic nameplates and diaphragm separator elements covered PTFE layer, should be installed in places and in a way that prevents electrostatic charging, in accordance with the instructions.
The diaphragm separator containing titanium elements must be protected against mechanical impacts.
The diaphragm in contact with the medium must not be exposed to an environment that could damage it.
Power supply of the transmitters should be compliant with the overvoltage category II (or better) in accordance with EN 60664-1 standard.
Flameproof joints are not intended for repair.

TRANSMITTER PROTECTION LEVEL (EPL) AND HAZARDOUS AREAS

Ga/Gb (Da/Db) EPL protection level means that the transmitter can be installed in Zone 1 or 2, and transmitter process connections can connect to Zone 0. EPL Db protection level means that the transmitter and process connection can be installed in Zone 21 or 22 Transmitters for mining applications Mb should be turned off if explosion hazard occurs.

PERMISSIBLE PARAMETERS OF Exd TRANSMITTERS

Ambient temperature range and temperature classes
Table 1. Ambient temperature range and temperature classes for Exd transmitters

*) for special version -50ºC
If the medium temperature can exceed Tamax, separating elements, such as diaphragm separators, siphon tubes, etc., should be used. The transmitter operating temperature Tp must meet the Tp≤Tamax condition.

Power supply, connection and operation of Exd transmitters
Connect the transmitter according to the electrical diagram (Figure 2). The transmitter electrical connections in potentially explosive zones should be made by personnel having necessary knowledge and experience in this area. The transmitters should be properly grounded by means of a grounding terminal. If the transmitter has metal contact with grounding structural elements or piping, separate transmitter grounding is not necessary.
Transmitter and equipment in the transmitter measurement loop must be connected in compliance with explosion-proof standards and conditions for application in explosion risk zones. If these rules are not followed, explosion can occur and people can be exposed to danger.

Termination resistor 120 Ω, which is by default included in the transmission system using a jumper between „Digital” terminals A and B (Aplisens PP Modbus boxes are factory equipped with resistor 120 Ω), should be used at all transmission speeds (especially @1152200 bps).

Table 2. Maximum supply voltage for Exd transmitters

In an explosion risk zone, do not remove the cover of supplied transmitter and do not connect to the terminals, and do not change the position of local indicator (display).

In order to secure the side covers against loosening, unscrew the hex socket screws pressing the screw heads against the edges of the covers. The method of locking the covers against unscrewing and the possible method of sealing the transmitter are presented in figure below.

No repairs or alterations to the transmitter housing elements and electrical system are permitted. Repairs on flameproof joints are not permitted. Only the manufacturer or a facility authorized by the manufacturer may assess damages and repair the device (if possible).
Due to the type of housing material (light alloy with high aluminum content), the user is obliged to ensure that in the transmitter installation site its housing cannot be hit and, consequently, damaged.
In a transmitter housing there are two holes for installing, one for a cable entry and second for a blinding plug with M20x1.5 or 1/2 NPT thread. As standard, the transmitter is delivered to the customer without cable gland installed. After consultation with the manufacturer, the user can purchase a transmitter with a cable gland, or without a cable gland and the missing cable gland purchase separately. A transport plug is installed in the cable gland place. In such case, the transport plug should be removed and appropriate cable gland installed (Figure 4) before the transmitter is installed. It is responsibility of the user to install a certified cable gland compliant with the list of equivalent cable glands presented in Table 3. List of equivalent cable entries. As a blinding plug, an Aplisens plug supplied with the transmitter or a certified blinding plug compliant with the list of equivalent blinding plugs in Table 4 can be used. It is allowed to install other types of certified cable entries and blinding plugs about marking Exd IIC Gb, Extb IIIC Db and Exd I Mb with at least IP66 protection and -40°C…75°C temperature range.
Apply LOCTITE 577 on the 1/2 NPT thread of cable gland before installation. When connecting, make sure that the cable type and diameter is suitable for the cable gland used and temperature in the installation site.

Table 3. List of equivalent cable entries

Table 4. List of equivalent blinding plugs

Use a shielded or unshielded, non-reinforced cable with compact structure and circular cross-section in an non-hygroscopic sheath made of an elastomer, e.g. YKSLY 2*1, YnTKSYekw 1*2*1, LIYCY 2*1.
If a cable of different design has to be used, it should be agreed on with the transmitter manufacturer in order to choose a suitable cable gland or individually purchase a cable gland suited to the cable used. The list of equivalent cable entries is given above (Table 3). The cables should be protected from damage by routing them in cable trays, jacket tubes, cable ladders, by using fixed mounts, etc.
When periodic inspections are performed, the covers tightness, cable entry and cable fixing in the cable entry should be checked. Visually check the housing and cable for mechanical damage, and the nameplate for legibility. The sensor diaphragm should be also included to periodic inspections. There shouldn’t be a signs of damage. During maintenance it is recommended to apply acid-free petroleum jelly on threads connection.

The diaphragm should not be exposed to damage during transmitter installation and operation. The transmitter diaphragm is made of stainless steel or Hastelloy and must not be exposed to contact with a medium that may damage it.
The connecting and operating general rules for an Exd transmitters should be compliant with the rules and standards applicable to devices in a flameproof housing: EN 60079-14 – Electrical devices in explosive atmospheres. Part 14: Electrical installations in risk areas (other than mines).
EN 60079-17 – Electrical devices in explosive atmospheres. Part 17: Electrical installations inspection and maintenance in risk areas (other than mines).
Due to possible damage, the transmitter should be protected from heating above 80ºC also when explosion hazard does not occur.
