In no event shall OMEGA be liable for consequential, incidental or special damages. CONDITIONS: Equipment sold by OMEGA is not intended to be used, nor shall it be used: (1) as a “Basic Component” under 10 CFR 21 (NRC), used in or with any nuclear installation or activity; or (2) in medical applications or used on humans. Should any Product(s) be used in or with any nuclear installation or activity, medical application, used on humans, or misused in any way, OMEGA assumes no responsibility as set forth in our basic WARRANTY / DISCLAIMER language, and, additionally, purchaser will indemnify OMEGA and hold OMEGA harmless from any liability or damage whatsoever arising out of the use of the Product(s) in such a manner. RETURN REQUESTS/INQUIRIES Direct all warranty and repair requests/inquiries to the OMEGA Customer Service Department. BEFORE RETURNING ANY PRODUCT(S) TO OMEGA, PURCHASER MUST OBTAIN AN AUTHORIZED RETURN (AR) NUMBER FROM OMEGA’S CUSTOMER SERVICE DEPARTMENT (IN ORDER TO AVOID PROCESSING DELAYS). The assigned AR number should then be marked on the outside of the return package and on any correspondence. The purchaser is responsible for shipping charges, freight, insurance and proper packaging to prevent breakage in transit. FOR WARRANTY RETURNS, please have the FOR NON-WARRANTY REPAIRS, consult following information available BEFORE OMEGA for current repair charges. Have the contacting OMEGA: following information available BEFORE contact 1. Purchase Order number under which theing OMEGA: product was PURCHASED, 1. Purchase Order number to cover the COST of 2.

Installation CAUTION: 1. INCORRECT ELECTRICAL CONNECTIONS CAN, IN CERTAIN CIRCUMSTANCES, DESTROY THE ELECTRONIC OUTPUT CIRCUIT. 2. BEFORE APPLYING ELECTRICAL POWER, MAKE SURE THE SUPPLY VOLTAGE IS TO THE CORRECT RATING. 3. THIS A VERY SENSITIVE SENSOR. ONLY APPLY PRESSURE WITHIN THE PRESSURE RANGE. Mounting Two M5 threaded holes in the base of the sensor provide mounting points. Note: The screws must not enter the holes more than 0.472" into the sensor body. The installed position of the sensor should be away from sudden temperature variations, shocks and vibrations and should not be close to strong electromagnetic fields (transformers, motors etc.). The sensor can be mounted in any position, but mounting at an angle may require zero adjustment. terminal zero adjustment block (fine) zero adjustment (coarse) cable gland span adjustment Internal detail Electromagnetic Interference To avoid electrical interference, use shielded cable with the shield connected to the earth ground at both ends. The ground of the sensor can be the casing or the ground terminal screw. Electrical Connections PX838 Series (current output) The maximum allowable load resistance is calculated to formula: R Max = 0.05 (V supply - 10) kW Where: R Max in kW and V in Volts PX838 Series (Unidirectional voltage output) Minimum load 2kW Note: Connections 5 and 6 are common. If the output cable passes through an area of electrical disturbance, use a recommended load impedance of between 2 kW and 10 kW. Connect the load resistance between the wires corresponding to signal and - terminal at a point furthest from the sensor; this produces a circulating current. PX838 Series bidirectional operation using bipolar power supply (±12 Vdc) with bidirectional output (0±5 Vdc or 0±2.5 Vdc) Connect the power supply to + for positive, -for negative, and 0 for neutral; connect the output to signal for positive and 0 for negative signal. SIGNAL0 Purging or de-gassing the sensor Two 5 mm hexagonal socket bleed screws are located on the outer casing and can be loosened to bleed the two pressure connections. Make sure that these screws are tightened after this operation. Note: It is possible to changeover the bleed screws and pressure connections enabling easier access or for installation in a difficult position. Adjustments Th...
