Series IS626 Pressure Transducer
Specifications - Installation and Operating Instructions
The Dwyer Series IS626 Pressure Transducer convert pressure into a
standard 4-20 mA output signal. The Series IS626 can be used to accurately measure compatible gases and liquids. Series IS626 full scale accuracy is 0.25% (see specifications). Designed for industrial
environments with a NEMA 4X (IP66) housing, this transmitter resists
most effects of shock and vibration.

ratings. Permanent damage not covered by warranty will result. This device is not designed for 120
or 240 volt AC operation. Use only on 10 to 28
VDC.
5. Wiring
An external power supply delivering 10-28 VDC with minimum current capability of 40 mA DC (per transducer) is required to power the control loop.
See Fig. A for connection of the power supply, transducer and receiver.
The range of appropriate receiver load resistance (RL) for the DC power
supply voltage available is expressed by the formula:
1. Location: Select a location where the temperature of the transducer will
be between 0 and 176°F (-18 to 80°C). Distance from the receiver is limited only by total loop resistance. The tubing or piping supplying pressure
to the unit can be practically any length required but long lengths will increase response time slightly.
2. Position: The transducer is not position sensitive. However all standard models are originally calibrated with the unit in a position with the
pressure connection downward. Although they can be used at other an gles, for best accuracy it is recommended that units be installed in the position calibrated at the factory.

3. Pressure Connection: Use a small amount of plumber’s tape or other
suitable sealants to prevent leaks. Be sure the pressure passage inside
the port is not blocked.
4. Electrical Connections
Wire Length - The maximum length of wire connecting the transducer
and receiver is a function of wire size and receiver resistance. Wiring
should not contribute more than 10% of the receiver resistance to total
loop resistance. For extremely long runs (over 1000 feet), choose receivers with higher resistance to minimize the size and cost of connecting
leads. Where wiring length is under 100 feet, wire as small as 22 AWG can
be used.

MAINTENANCE
After final installation of the pressure transducer and its companion receiver, no routine maintenance is required. A periodic check of system
calibration is suggested. The Series IS626 transducers are not field repairable and should be returned if repair is needed (field repair should
not be attempted and may void warranty). Be sure to include a brief description of the problem plus any relevant application notes. Contact customer service to receive a return goods authorization number before
shipping.

3. (ENTITY CONCEPT DEFINITIONS)
IMPORTANT! NO REVISIONS WITHOUT
PRIOR UNDERWRITERS LABORATORIES
APPROVAL CAN BE IMPLEMENTED
THE ENTITY CONCEPT ALLOWS INTERCONNECTION OF INTRINSICALLY SAFE APPARATUS TO ASSOCIATED APPARATUS
NOT SPECIFICALLY EXAMINED IN SUCH COMBINATION. THE CRITERIA FOR INTERCONNECTION IS THAT THE VOLTAGE AND
CURRENT WHICH INTRINSICALLY SAFE APPARATUS CAN RECEIVE AND REMAIN INTRINSICALLY SAFE, CONSIDERING FAULTS, MUST BE
EQUAL TO OR GREATER THAN THE VOLTAGE (Voc) AND CURRENT (Isc) LEVELS WHICH CAN BE DELIVERED BY THE
ASSOCIATED APPARATUS. CONSIDERING FAULTS AND APPLICABLE FACTORS. IN ADDITION, THE MAXIMUM UNPROTECTED CAPACITANCE AND
INDUCTANCE (Ci & Li) OF THE INTRINSICALLY SAFE APPARATUS. INCLUDING INTERCONNECTING WIRING. MUST BE EQUAL TO OR LESS THAN
THE CAPACITANCE AND INDUCTANCE WHICH CAN BE SAFELY CONNECTED TO ASSOCIATED APPARATUS.
4. INSTALLATION MUST BE IN ACCORDANCE WITH THE NATIONAL ELECTRICAL CODE (NFPA 70, ARTICLE 504) AND ANSI/ISA-RP12.6.
